I recommend not creating a new account if you can help it. I believe multiple accounts are against Amazon ToS and could cause further problems down the line.

I would use any info that you have in terms of where Amazon sends your revenue to help.

Agreed.

Sellers can have multiple Amazon selling accounts, but you need to be able to demonstrate a legitimate business need to do so. Source: https://sellercentral.amazon.com/se.....e-9308193a7f66 . This situation probably would not qualify -- they'd want Ziel to pursue account recovery.

I would suggest  Ziel contact customer support again. If he's withdrawn money to a bank account, having those bank details would help. With his legal name, bank details, email address, and phone number, that should be enough to get an agent to help him recover his account.
