AM I BEING ****MED?

I have been using FNB for a about a year. All has been okay until early October when I got a call from Charity Khoza. I was expecting a deposit from Swaziland and according to her it needed to be invetigated for potential *****. Which is understandable as banks need to protect themselves but my conversation with her it felt like she had already decide the transaction was *****ulent as I was receiving the money on behalf of a foreigner friend who did not have a bank account, mind you the first transaction went through fine without issues. Maybe FNB operates on the assumption that one is guilty until proven innocent. Charity said the investigation will take two weeks and I will be informed of the outcome. In the third week I call on Monday to find out wht is happening and the call centre guy says he spoke to Charity she said I have been informed of the account termination, which I had not. But yesterday I suddenly get notifications that my account is terminated, I've tried speaking to Charity but nothing. I've also sent an email but no reply. That accout I was using for my salary deposits and because of one transaction (which I feel she had forgotten about until I called) I don't have an account anymore. I need you to please make me understand your investigation process as I feel I am ****med or something.
