Closing an account: Checking or savings account

I am requesting an update regarding the restriction placed on my account. My account was opened approximately one month ago, and the only activity I have conducted has been depositing my own funds. Since the restriction was placed on my account, I have been calling daily and have only been informed that the account is still under review, without any estimated timeline or additional information. At this point, I would like to request that my account be closed if the restriction can not be resolved promptly. I also request the release and return of my remaining funds as soon as possible. I would appreciate a clear explanation for the restriction, an expected timeframe for the review, and the next steps required to resolve this matter.
