Based on the thread link you provided, I believe your issue has not been attended to either because the team has been very busy or because you have not convinced them enough that you are the rightful owner of the account since there is already another active account that also has the same claim to account ownership.

One user claims to have the older Ethereum address used on the account since 2018, and you claim to have a Bitcoin address, which you have managed to sign in with, but the other user hasn't because a Bitcoin address is the only valid way to use it. I also noticed most members did not agree with your used address and proposed you use an older address, which you haven't, which I think might add to things that make your issue pending to date. I don't know, but it's just my guess.
