Issue gaining access to my seller account.

So I’m locked in a battle with amazon, and I can’t get them to respond at all. I have an old seller account from 10+ years ago. If I try to log into it I get a restricted or “you don’t have permission to access this page” error. I assumed they closed it so I tried to make a new account. I went through the entire verification process for them to deny me because I already have an account registered. I wrote an email to the appeals email address that they provided, but I haven’t heard back from them. I basically asked for them to either give me access to my old account if they can’t issue me a new one. I’ve tried using the chat feature, but they told me that they can’t help me, and they also can’t give me a phone number, or to request a call back because I don’t have a registered account, which the irony is not lost on me.

Basically I’m here to ask what my next steps are. Should I just completely delete the entire old account (which currently is home to my decent audible library), or do I wait to hear back from amazon? Is there a phone number that I can actually call that will get through to someone that can actually help me right away? Any input would be appreciated.
