Uncaring card disputes division

I had a R5000 deposit returned from an Auction to my account which to date has not reflected in my account . Numerous mails were sent between Auction Admin to their merchant Standard Bank but my Bank ABSA don't care to help or even respond to any mails I've sent . The card disputes division sends an automated mail response and the ABSA mails being sent to Neville Brown just get no response at all. It's been a month and a few days since this transaction but ABSA my bank don't seem to care to help me . I've been running calling begging but it seems that standard as their staff don't seem to care .
