This attitude of theirs is why I'm never going to recommend or use AWS. When we first decided to evaluate if AWS would be a better fit for us over GCP, they never let our company get past their account verification.
We're a small US based company, just a few people. They required verification documents, business registration all a real headache. After all of that we couldn't use a single thing to run, not even cloud shell. It's as if the account was disabled in some very obscure way. We spent 2 weeks arguing with support to please reinstate access to our account, and after 4 false "it should work now" responses they told us to start paying for premium support.
PAY PREMIUM TECHNICAL SUPPORT FOR A SERVICE THAT WE NEVER GOT ACCESS TO OR USE.
