They do not want to make money

I have a dual Markham card - but I use and pay the account. This afternoon I was at Markham's in Kimberly - Diamond Pavilion - where I wanted to buy my dad - the account is in his name - some clothes with more than R3000 for Father's day. When I got to the till and my card not registering after the swipe the lady at the till first called customer service - and they wanted to speak to my father which was 30 kilometers away. The cards has been doing this for a while but here in Pretoria the stores still helps me. Markham's should please tell me if they do not want business or money in future. I had this account for a very long time and always pay this account - if this is the case I will cancel this account. Me and my father do not have time to sit around the whole day or just randomly walk around in a mall we are very busy people. I think the service was *********** from the Call Centre and the store. I buy at Foschini and Fashion Express on a regular basis - but please tell me if I can rather close this account in order to avoid such utterly *********** people and disappointing service
