FNB not helpful at all, very useless

I was ****med by people called Autodealer SA with another name renttowon sa, I app**** to buy the vehicle with them, and send all the required documents and was approved, later on I was asked to pay R650 for ******** verification/vetting and that check out positive, then I was asked to deposit R1500 for vehicle delivery cost fee for inspection and test driving before i can take the vehicle, only later on to realize that I was ****med as i tried to contact them, and only promised to deliver the car, then I called FNB ***** department to report the matter withe the hope that my money will be returned, FNB(Desiree Moonsamy) emailed me back and requested that I open the ***** case and write the affidavit and send them back, which I did and after three(3) day, I decided to email her back, and within 2hours she emailed me back with the a regret they tired to recover the money but were unsuccessful because the money was utilised in the utilised in the implicated account, which one is FNB account were i paid R1500, how is that possible? I can bet she never even tried to investigate my case and this shows that FNB is supporting the **** going around the country ripping people off their hard earned money, I urge people to move to another banks, FNB claims to be the best bank in SA, but from my experience they are not helpful at all, I will be closing off my account before the end of January
