I can still hope the admin can help me with this. I don't want to lose my legitimate account and so far the only proof is the registration email I have.
I didn't expect it to be this complicated, I can't prove anything about the old wallet because my phone was broken for a long time and nothing of value was there. I forgot all my wallet credentials because I don't have anything of value there and having another wallet is easier than having to keep it for years.
Hope admin can solve my problem. That email is the only hope at this point.
