They seem pretty good at writing back to people. Have you contacted them? It's normal for new accounts to get suspended pending KYC checks. But they also do the checks pretty fast.
That’s pretty suss. Just send your passport and if they have any issues with it, they’ll ask. If they ask you for your passport and you ask “how do I comply” I’d probably suspend the account to since you seem unable or unwilling to comply.
It’s obviously a typo or something similar. The customer support person likely has no idea what you’re talking about, they want a passport with your name on it, they don’t care where it is from.
