Hi, im the real owner of the bitcoin wallets
You know that ownership has to be proven, right?
If you don't have account info or even better the private keys, I'm not sure who can help you.
About blockchain.com,
if you have been using their services for those wallets, you can try their support (although imho your chances are nearly 0). And this would mean that you can prove you had an account there and they will provide you your private keys or a working account.
"Anyone from bitcoin" clearly cannot help you. That's is not a private company and the only way to access those funds is if you have the private keys.
Yep it’s how it goes not your keys not your coins OP. I hope you can somehow manage to get back in if they are yours. I’m not sure what else you’re going to do but maybe if you kept all the hardware even if there is water damage you might be able to somehow gain access with a trusted professional.
