I got the address stored in Safello. I sent the bitcoins before i restored my Electrum wallet,cause i took for granted that the receiving address would be there like it always has.
Then it sounds like you have sent coins to an address you never controlled, which would explain why A) they never turned up and B) they have since been moved on without your input. Whether this was from a bug on the Safello platform, your account being hacked, or some local malware, I can't say.
I dont think the wallet it self has been stolen,however the particular bitcoin address that i have sent to is gone.
If the wallet you are recovering with your seed phrase is showing no transaction history whatsoever, then the address(es) you previously used are quite simply not generated from this seed phrase. Whether they are generated from a different seed phrase, or from an additional passphrase, or whether they were imported from an external source, we can't say.
The only way to tie these two issues together (your seed phrase not recovering your address, and the funds on that address being stolen), would be if an attacker had interfered with how you set up the wallet in the first place, allowing you to generate a seed phrase and a wallet, but then replacing your wallet with one in which they know the seed phrase and/or private key(s).It might been so. I am checking further. Thank you all for the help.
The issue is now solved and i can now access my Bitcoins!
The issue was so ridiculous why i could not see any history when restoring the wallet. First time i created the Electrum wallet a recevied a 12 word seed phrase which i wrote down on paper. I uninstalled the Electrum wallet and then reinstalled it,receving a new 12 phrase word seed phrase,which i wrote down on a paper.
Now after having uninstallning my PC and downloaded the Electrum wallet,and without thinking i wrote the 12 word seed phrase,which was for the new wallet. That was why the saldo was 0 bitcoins.
Now i uninstalled my current Electrum wallet with 0 saldo,and downloaded it again,now writing the right 12 word seed phrase that i received from the other earlier first Electrum wallet. Voila! Now the bitcoins is there!
I did not reflect that there was two different phrases between these wallets. I first simply wrote down the 12 word seed phrase from the paper i found in my wardrobe.
I must be half senile or something,not remember that.
Tonight i searched further in the wardrobe and found the other paper with the other 12 word seed phrase,which i completly had forgot. These 12 word seed phrase was the right from my first Electrum wallet. Now my Electrum wallet is restored,and i have all bitcoins intact.
The Bitcoin address that i had sent bitcoins to from Safello,that was previously missing is now there.
There was no malware,hacker or bug involved which i am glad it was not! Just the wrong 12 word seed phrase.
Thank you all for contributing with help and advice,but now the issue of the missing coins is solved.
