Apple Developer Enrolment Revoked?

Back in July, I successfully enrolled and paid the annual fee. However, in August, the "enroll" button reappeared as if I hadnt done it. The app is still available to download on App Store, but I cannot update it, cannot fix the bugs at all.

I tried to contact the support team multiple times but it has been more than 1 month and there's no update so far. I was told that the app was active, then it went inactive, which triggered some concerns. It was first reviewed by the senior advisors but now it's escalated to the internal operation team (sounds serious). Anyone has the same experience or knows someone who knows? I really hope to know the reason as well as how high I should keep my hopes up.
