Smule Closed My Account With No Warning or Explanation After I Paid for VIP

About 4 days ago, I created an account on Smule with the username BaBa_Krall and purchased an annual VIP subscription for this account. However, today, my account was suddenly closed without any warning, notification, or explanation being provided.

I don't believe I violated any rules, and I wasn't given any explanation, either by email or within the app. I'm now unable to use either my account or the annual VIP subscription I paid for.

I'm requesting that Smule review my account, username BaBa_Krall, which was closed without any explanation, and reactivate it, restoring my access.
