FNB can't stop *****

I have had charges debited from my account that appears to be ***** and all FNB does is bounce me from one department to the next, each telling me they can't help me. After four different departments the last operator just hung up. My card could have been compromised but instead of trying to stop the theft each FNB call centre operator basically says its not their job to help and then just passes me along. Is ***** not supposed to be a priority? Who will refund me if my account is wiped out?
