Cheque Card Declining

Master Card Declining everytime I swipe at a store. I thought it was daily limit so therefore went to a branch in Benoni where they checked card is fine and working... And apparently Elite accounts there isn't a swiping limit. So I was placed on the phone to check for any blocks/lock-up on the card and according to consultant at the Card Division my card is fine so was transfered to order a new card but the consultant rudely refused and requested to speak to branch consultant then hung up. I can withdraw with my card but even a in-store purchase of R50.00 doesn't go through... What annoys me is who is this consultant to tell me I can't order a new card while the one I have isn't fully functional. It's really embarrassing having to transfer funds to other accounts when I purchase. So basically standard bank consultant are telling me to live with this error as I'm denied \permission"to order a new card which I'll be paying for. I was able to swipe before"
