Additionally it is pretty strange that your email is no longer attached to your account. But this account should still exist and therefore a login should be possible.
You should contact the blockchain.info support for instructions how to regain access to your wallet.
If you get access to your wallet again i would highly recommend to use a wallet where you have the control over your private keys and therefore your money.
Doesn't matter whether a desktop, mobile or hardware wallet. Each of these is safer / more secured as an online wallet.

Hi, yes the 12 words are correct. About the email, I did this https://blockchain.info/wallet/#/reminder and now it shows 4 Wallet ID-s (the ones that were created after I lossed the password, generated with the 12 words with only 1 address in it. Why 4? Because I tried 4 times to recover my wallet (read: FUNDS)
But the initial, first wallet ID doesn't show anymore. I have tried to contact Blockchain.info but there is no reply. It is very very busy there I assume...
