This is their response:
Thank you for your message.
I am afraid that no manager can resolve this, as we have been telling you, our wallets are non-custodial, we are unable to make the change you are asking us to do. We cannot change its email address as your wallet is non-custodial only.
...
It is ridiculous how they can boldly write this in a response being centralized as they are. Users will not be getting into thee issues frequently if their wallet was truly non custodian.
Blockchain are completely ignoring me now.

Chances are it was an inside job as I had left the wallet without any intervention since 2014.
It very possibly was and they are aware that the funds there have been long spent. They have terrible customer support service and even worse security protection.
