Cheque Card *****ulant withdrawal

I lost my cheque card on a Monday 27th Nov 2017. After looking for it I could not find it. I then locked on to my banking online and discovered that R2 000 was already draw from the account. I called Standard bank to cancel the card. The customer services told me that the money was drawn at a FNB Benoni 10:30pm on the 28th November. I must register a claim and they investigate. the process will take 5 to 6 working days. I never got a call from the bank and every time I called I was told it is in process. I called them 5 times. I receive a call on the 13th December advising my that my claim was resolved and the bank will not refund me as the card used to draw was my original card and that person had my pin. I don't understand how. I have asked for footage which they cannot provide. I find the bank simply don't care and my money is not secured with them.
