Ask HN: How can I set up an Instagram account if I keep getting Instabanned?

This must seem like the dumbest question ever, but every time I try to set up an account for my business via the website, I get "Something went wrong please try again later." Then when I try again later it tells me the email/username has been taken (I'm running out of ideas for usernames now that make sense for the business). If I try logging in with the supposed failed sign up credentials I get told that the account has been banned for violating the terms & conditions (not sure how I can violate the T&Cs without ever having logged in or even successfully sign up). Visiting the help pages for Instagram gives some promising forms to fill in, but upon submitting I get a "This page does not exist." error showing up.

I did manage somehow to get hold of a human, perhaps via support@instagram.com, but they told me to go see the help pages and fill in the broken forms, and when I replied that they are broken they told me "I cannot help you through this channel". (so much for "support")

The help pages mention that to appeal a banned account I must use the App, but I don't really feel like installing the App given how useless the experience has been so far. Is this really the only way I can resolve this?

Any ideas on how I can get this fixed, help me please HN!
