FNB have no customers at heart

On the 23rd of May 2015 (Saturday) I went to FNB ATM at Palm Ridge, I withdrew cash a fair amount... After that I used my card to swipe and for fuel. The following day my money had been withdrawn without my knowledge thereof, As I had my card with me at home. Then on Monday I went to FNB to go and open a ***** case, they took my card and they destroyed my card they told me that they were going to investigate the case, they were going to refund me my money after three weeks after the investigation had been concluded. They then sent me an sms telling me that they were going to refund me on the 01st of July 2015, so now I gave them a call, now they refuse to give me my money. they say that the money that was ****** from my account was withdrawn with the same card and same pin. How can they not go and look on their ATM camera's that I was personally not withdrawing cash at that time. if they did a proper investigation then they would have seen that it is not me.
