No respond after a reported case

I was ****med money which I deposited it to an fnb account on the 09-08-18, after I realized that it was a **** I called fnb ***** department on the 11-08-18 and the requested and affidavit and on the 20-08-18 I emailed the everything that they requested and seems then they have been quite. I've send several emails and no respond, and always when I call they tell them the nothing logged on there system. This is the account no that I deposited money into ********** 1946, the owner is P B Chipangamati.

So if banks cant help us in dealing with **** who is going to assist us, or does the mean the fnb ***** department works with those ********? Guys help us please..............,.
