I bought a gift on amazon.com.au via VPN since I'm based elsewhere. They "detected suspicious activity" on my account and froze my account across all amazon platforms. Now I had to provide evidence that it was in fact me, who ordered (which I did) and promised to review within 1-3 days. It's been a week and my account is still frozen. And no one answers my multiply query emails either. I can't use the customer service, because, guess what, you have to log in to use it.
