Consultant insulted me and withheld my ID

I went to the bank to get a new card since I lost my old one, and I wanted to withdraw money that recently was deposited into my account. I was told by the consulted that my account has been blocked due to ********** activity which I'm not aware of. She asked for documents to prove how the money was deposited into my account, and I brought a statement, an affidavit and my ID. Takalani went on to insult me saying that I don't look like I would have that kind of money in my account and that I'm a *********. She withheld my ID and refused to give it back since Forensics is apparently still busy investigating. Why didn't the bank contact me when ********** activity began on my account? For about 3 months I've been having this account and only now when I have money deposited into my account and I want to make a withdrawal, I'm told about *****. The consultant shouted at me in front of other clients, did not call a manager to resolve my issue. After pretending to log a call with Forensics, she asked me why I was still there since it was clear that I am going to jail. After I had been humiliated in front of clients, left the bank in frustration with my ID still withheld. I need your help.
