Funds disappeared from my bank account

I don't know why they just don't close this bank once and for all with so many bad reviews. Well here is another one I received funds in my account then next day funds vanished from my account without any communication or warning from the bank. When I went to one of their branches to find out what happened they said my account is suspected of being involved in a **** I asked how the response was never clear to me this was a week ago till this day I haven't heard any feed back on the investigation they do when they Suspect such from an account and i have not received my funds back into my account. Honestly do know why I'm hoping they will return my funds because of the type of bank I'm dealing with
