Claude Pro Account Banned One Day After Paid Subscription Purchase

I purchased a Claude Pro membership, and just one day after my purchase my account was suddenly banned. Since yesterday I have been unable to access my account and can only see a message stating that my account has been disabled after an automatic review, with a “Retry” button that does not resolve the issue. I did not receive any prior warning or clear explanation about why my account was banned, especially right after I became a paid member. I contacted Anthropic support about this situation, but so far I have not received any response. I request that my account be urgently reviewed, that I am informed clearly about the reason for the ban, and that my account be reactivated.
