Kind of long story and since I'm not native English speaker I'll try to be concise -
1. I have 2 wallets on blockchain.com, opened few years ago.
2. I've made a transaction from wallet A to wallet B.
3. Haven't tried t ologin for several years.
4. Recently I've logged in succesfully to wallet A - I use my gmail as 2FA.
5. Tried to log in to wallet B - didn't get the confirmation mail.
6. After few days - tried to recover my 2FA and then I saw that for wallet B I've used a different mail account, which I've closed.
7. Applyed for the company to change my 2FA account - after couple of weeks got it confirmed.
8. When trying now to login to wallet B I get the verification mail, but when I press the link in it I get an error - cannot decrypt wallet
9. I've tried to use the recovery phrase - I've had some issues with that too, because I have 17 word phrase, not 12.
10. After another mail to the company, they replied that my wallet is a legacy wallet and sent me a link for legacy recovery, that accepts 17 words.
11. My recovered password is the same as the one I have, but I still can't log in.
It looks like somethong has gone wrong in the process of changing the 2FA mail, because I don't have any problems with wallet A,
but the bottom line is that I have the correct password and yet cannot access my wallet.
I've written to the help desk, but all I get is some standard reply that they cannot recover my wallet.
Does anybody have an idea?
Regards - Tuco

Complicated case. Can you please check if you have saved somewhere your wallet file (JSON file)? If so then it would be easier to recover your wallet. The problem is your verification links from the mail isn't working. So, only support could help you in this case. The recover phrase wouldn't help here to recover your wallet. Most likely it was just to recover your wallet details like wallet id or password/2FA. You can't import this seed to any other wallet since this isn't compatible with any seed phrase.

However, if you access new mail and receiving 2FA links, so most likely you can download your wallet file somehow. Most likely you may take a look at this video, brut force blockchain wallet.

What's the actual error? Because if the password is incorrect, it would be:
Code:
Error decrypting wallet. Wrong password
If you're sure that the password you've been typing is correct, then the issue must be their server's encrypted copy.
Try to use a different browser, PC or clear your browser's cache; if it didn't work, Blockchain.com is the only one who can help you with this.

FYI, a user will be prompted to enter 2FA code (if enabled and email verification if necessary) even though the password is incorrect, the error will appear after.

Old blockchain.com wallet is not injected in new software update. so if you have old accounts you can recover it use your wallet seed.
your old account, usename, password and 2FA will not work
if you have 17 wallet seed contact support team (dont give them your seed names) and you can recover it with new account. export your private key and import it to any wallet here https://bitcoin.org/en/choose-your-wallet

I do have an AES file of a wallet, I'll try to decrypt it. Chances are that it belongs to the wallet that I can decrypt...

The problem is your verification links from the mail isn't working. So, only support could help you in this case. The recover phrase wouldn't help here to recover your wallet.
I also think that the problem began when I've had to change my verification mail. The site's support isn't very helpful so far. I'm considering to open a new mail and to use it as a new 2FA, maybe it will reset something in the system.

Code:
Error decrypting wallet. Wrong password
Yes, that's the error I get. The password is 100% correct, since it's the same password as I get if I use the recovery phrase.

Try to use a different browser, PC or clear your browser's cache; if it didn't work, Blockchain.com is the only one who can help you with this.
Already tried another browser and clearing up the cache - no luck, so I gues tring a different PC won't help either.
Anyway - thanks for your advices.

I have 2 wallets, both were created on the same day, yet I have access to one of them.

if you have 17 wallet seed contact support team (dont give them your seed names) and you can recover it with new account. export your private key and import it to any wallet here https://bitcoin.org/en/choose-your-wallet
What's the exact procedure? Just to ask them to recover it by the public key?
How do I export and import my private key?

UPDATE: I've found the wallet.aes.json file of the wallet and was able to decrypt it with the same password that the site claims is the wrong one.
What should I do next? Should I "import" it (using this link - https://login.blockchain.com/wallet/import-wallet)? It is already in their system, so maybe "importing" isn't the right thing to do.
Can I use this file to gain access to my wallet from another site, or is this file unique to blockchain.com?

Importing it to that link (the correct link) will create a new wallet with different Wallet ID and other credentials, but the keys from your imported wallet.aes.json will be added there in a separate wallet.
Better use it only if you have no other options.

Yes, you can decrypt the file to get an unencrypted 'wallet.json' file to view the contents in readable format.
Like in this reddit post about using OpenSSL: restoring_blockchaininfo_walletaesjson_file

Others may have a better solution.

@nc50lc -Thanks for your answer.
Yes, you can decrypt the file to get an unencrypted 'wallet.json' file to view the contents in readable format.
Already did that, that's another proof that my password is correct, even though when I try to use it in the site I get the "Cannot decrypt wallet, wrong password" message.
But what can I do with that file? Can I use it to transfer the wallet to another one?

Importing it to that link (the correct link) will create a new wallet with different Wallet ID and other credentials, but the keys from your imported wallet.aes.json will be added there in a separate wallet.
Better use it only if you have no other options.
I don't understand what it means - will I end up with two wallets, one inside the other? And yes, I didn't copy-paste the right address, it is https://login.blockchain.com/wallet/import-wallet

It seems you forgot some character from your password or you put an extra character from your password.

Why not try to brute-force the wallet to find the right password for this file "wallet.aes.json" there is a free tool that you can use to recover the right password.

Can you check this tool https://github.com/gurnec/btcrecover/blob/master/TUTORIAL.md#btcrecover-tutorial
Supported blockchain wallet (v1-v3 wallet formats, both main and second passwords)

It sometimes happens to me that I remember the right password but didn't work but it solves my problem when I use a brute-force tool and see some extra character on my password that I forgot.

There are actually multiple wallets in a single blockchain.com account, you can create multiple wallets in the "Settings->Wallets & Addresses".
With that in mind, they will include the keys from that backup into a new wallet, that wallet json backup will still be useable as long as they'll not sweep the keys but AFAIK they will just include them in a separate wallet.
BUT I haven't tested it in the latest version so it's best to use that as the last resort.

It's a JSON file and should be readable, you can open the decrypted wallet file (wallet.json) with a text editor and look for WIF private keys in there (51/52 character that starts with 5, K or L).
Do not post them here.

If you see random characters instead of a json format, then it's most likely not decrypted properly, corrupted or the password used was incorrect.

My bad, didn't explain my self right.
The file that was in my pc is wallet.aes.json. I've successfully decrypted it and it has among other things my guid (I believe it's also the "private address"), my wallet address, two keys - priv which is 44 characters and priv_sipa which is 51 characters starting with 5 and also sharedKey.
What can I do with this file, if blockchain.com insists that my password is wrong?

Since you've already got the "priv_sipa" key (a.k.a WIF prvKey) [Source], you can import it to any client/wallet that you want to be able to spend its balance (if it has).

One example is Electrum: Bitcointalk thread | website | Github Repo
You can download it from the website and import the private key using the option "Import Bitcoin Addresses or Private keys" instead of Standard wallet in wallet creation window.
But before that, make sure that you're using the correct version and verify the signature (tutorial link) of your downloaded Electrum before proceeding.
Also, you might want to import the key(s) offline and just check the balance using the addresses online ("View->Show Addresses" then open Addresses tab).
