Bad service

I visited STANDARD BANK [Lakeside] to ask for assistance with my current account card that was giving problems sometimes when I swipe to make a purchase. They were not very helpful and referred me the call center. I explained to the agent that when i swipe with me card to make a purchase, it sometimes doesn't read the card . Will they be able to replace my card, as I had it forever and it expires next year. The agent [Nero minded and trained like a donkey] advised me that I have to pay R120,00. I advised the agent that my card is not reading on the swiping facilities. I struggled with my card and decided that it was time to change banks as my bank is not willing to listen to me. PLEASE ASSIST WITH CANCELLING MY CURRENT ACCOUNT ? . STANDARD BANK has to many clients to listen to the little people.
