Card stopped for all Point Of Sale (POS) functions

I discovered on Friday the 15th of May 2015 that my card was unable to withdraw money. I proceeded to do shopping and when i wanted to pay, the POS system and teller said that my transaction had been declined. After a few more attempts, i had to leave the store embarrassed as i was unable to make the purchase. When i called Standard Bank, the consultant said that there was no issue with my card. Today, 19th of May 2015, was the first day i could get to the bank. I spoke to a teller called Norma Pila at the Boulders, who was immediate able to tell me the issue once i described the problem. <br> She told me that my cheque card had been disabled for all Point Of Sale transactions whether it be card swipes or ATM withdrawals. She said that i am not the first person she has had the issue with. She issued me with a temporary card and said she would investigate. I would like to commend her on her professional and efficient attitude.<br> <br> So my main issue is that Standard Bank did not inform me in any way about this issue and their call centre staff are unable to identify these issues. I have also incurred additional bank charges as a result of having to use other bank cards.<br> <br> Explanation Please?
