Inefficiency at Standard Bank Southdale

Southdale branch and card division are frustrating me. This issue started around April 2015. On several occasions I have been going to the branch because my card is dis-functional and no one seem not to know why can't my card swipe. I was given a new card with the same problem. I then called card division several times they said there's nothing wrong with the card meanwhile my card is not working. All my accounts are held by them, if I struggle with a card what more all others. It is now enough
