Foschini Helpdesk - The customer is not important!

My Foschini account was one of the first accounts I have ever opened. I have been managing my account great and always paid more than the amount due. 2 weeks ago I had a terrible experience. I was at George mall in Foschini with purchases I wanted to make. At the till they said that they can't swipe my card because It's damaged, they want to issue me a new card. Then I had to speak to someone from "Helpdesk" asking me a lot of questions (and the lady who spoke to me did not speak English very well, I could hardly hear what she was saying)... So there I was standing with the purchases that I could not make. Now apparently I have answered the questions wrong and I need to take in 3 months bank statements to have my card opened. The lady at Foschini George looked stunned while talking to "Helpdesk", asking her what she must tell the client? Then I went to Riversdale Foschini and took them the statements and asked if they can issue me another card because George Foschini said that my card won't swipe and they can't help me if I want to do purchases? Foschini at Riversdale swiped my card and it works perfectly, they tested it more than once. They say they can't issue me another card if my card is not damaged... my card do have a little dent(bent) at the top corner... but it swipes at Riversdale, but not in George? But Riversdale don't want to issue me a new card? Now my question is: "What must I do if I want to go and buy stuff at George again and they cant swipe my card"? I have been a loyal client for so long, but no one seems willing to help me or give me the correct answer. Because is the problem at George that they don't know how to swipe a card? Is the problem at Helpdesk (who should actually sound like they want to assist and be able to communicate clearly), who should have explained things better? Or should Riversdale issue me a new card (even if they can swipe the card)?But George can't and I complained about that? I would really like some assistance with this, because I am stunned by the way that Foschini is treating their customers (client satisfaction is not important). Foschini is always fast if they want you to subscribe to a magazine or something like that... but now? Or am I just expecting too much of a company that I have been a loyal client of for many years?
