Hello Yo Account Banned for Serious Violations Without Explanation

I am writing about my Hello Yo account, which is linked to my Facebook login on an Android phone, and which was blocked about two weeks ago. When I attempt to log in, I receive a message stating that my account has been banned due to “serious violations,” and I can no longer access it. I do not know what specific violation is being referred to and I believe there has been a mistake. I would like my account to be reviewed and the ban to be lifted so that I can use my account again. My account ID is 1584878***. I kindly request that you re‑examine the decision taken on my account, inform me clearly if there is any specific issue, and, if possible, cancel the ban and restore full access to my Hello Yo account. I also ask you to inform me clearly, and as soon as possible, whether my account will be restored and when I can expect it to be accessible again.
