The AWS account is unresolved due to security restrictions

My account was judged to be at risk of intrusion, when I received such a reminder email, I needed to upload it to my account to answer one to four questions, when I checked one by one and then changed the password, reset the MFA device and access appropriately, and all of them were all correct, and then replied to the online assistant when he contacted the security department to lift the audit restrictions, and after ten minutes, I received an email reminder that it had been resolved, but did not give any reply to inform whether it had been lifted, When I log in to the account again and find that the case has been solved, but I go to check the status of the account or it shows that it is restricted and cannot enable resources normally, I go to open the case again, and the online assistant gives me a reply that he doesn't know what caused the case to be automatically closed, he will contact the security department to follow up, I remind not to close the case again, but after two minutes, the case is automatically closed again, but the problem is not solved, why can the case be automated, I have been using it since 2017, Just because I changed the access region and was judged to be the first intrusion, after answering the question, I was judged to be the second intrusion, and then I answered the question again to cause this situation, I hope that the relevant team can deal with the account immediately and restore the restrictions, I am really anxious, aws account email: **********
