So I replied to them in a more stern manner this time and once again asked for the email to be changed back to the set-up email. 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.
 
Additionally, if there is an email change that you may not have done, it means that this account has been compromised, a third party may gained access to it and in turn changed its email address and even likely its login password that we cannot know of. What we have been telling you is that there is noting else we can do to assist you when it comes to regaining access into that account which account has not been accessed for multiple years now.
 
We cannot also know if there are any funds held within that account either.

As a non-custodial wallet provider, we do not have access to or knowledge of the addresses within users' DeFi Wallets, nor do we have access to users' funds within those wallets in any way. This helps protect our users' security and funds from malicious parties; however, it also means that we have limited information about them.

You can learn more about how our wallet functions with the information below. Sorry that we could not be of more help.
