From having been behind the scenes of a web hosting company a while back: They almost certainly have decided that you're a scammer, and that any account you ever try to open is just an attempt to get around being banned for being a scammer.

The complete non-answers from support are almost certainly because they have that as a standard policy with people they've decided are scammers, because the genuine scammers out there are extremely good at manipulating literally any kind of even vaguely permissive support policy into enabling further fraud.

The bigger issue here is that when a company is actually good at this stuff (like that web hosting company I once worked for), there's a department specialized in handling these cases with knowledge of how to properly verify legal identities and filter out the scammers... but quite a few companies today both big and small have decided (possibly correctly, given how they're treated) that it's easier and more profitable to just skip that entirely and instead leave false positives locked out of the system permanently.
