account linked

I had closed my UK market account, and after some time, I created a new account with a different email in the UK market. Now, my new UK market account got linked with the old account's seller name that I had closed. I have submitted several appeals stating that I had closed the account with that name in the UK market. However, the appeal support team is requesting evidence, specifically the emails received when closing the account. I submitted screenshots of all the emails as evidence, but the appeal support team did not accept them. What kind of evidence should I arrange? Please help.
