Amazon denied me opening a seller account, doesn’t seem to want to help at all?

Has anybody been inexplicably denied? I’m a US citizen, uploaded my drivers license and bank account statements, made sure all names / addresses matched. A few days later I get denied, with the message:

Your request has been rejectedWe are unable to verify the documents you provided. As a result, you may not sell on Amazon. We cannot give you more information about this matter, and we may not reply to further e-mails about this decision.

I message their support, they say they’ll look into it and email me, the email then says that:

Why is this happening?
The documents that you provided do not meet our policy requirements. We are unable to share further information about this matter.

AFAICT my documents meet all their requirements. Anybody else have this happen before? Seems they don’t even allow me to upload alternative documents.
