Standard stole my money

I have been using Standard Bank for about 8 months now and recently I received a payment from my employer then Standard Bank blocked my account without any valid explanation I went in the branch they said they are suspecting ***** so I should submit POP and an affidavit, I did that then they told me the account is already closed the ***** department will call well this is now the second month and still haven't received a call from them going back to the branch is useless because I'm not getting any answers. Did Standard Bank ***** my money because there is no explanation on why they closed the account or where the money went.
