Bad treatment/service

In July 2015 I went to Foschini using my Luella card to buy. They told me that I cannot use it anymore because Luella has closed. However most of the Foschini shops still sell Luella shoes. It's confusing how can they close while they are still selling their shoes and every season they change. When I went to Foschini to buy I was told to pau off my Luella account and they will open up a courtesy account for me which they did however I am struggling to buy with the courtesy account however they accept payment on the card. I look like a fool every time I go to the till to go and buy with my card and they cannot help me. I called the call centre and spoke to the following people Tahira, Lyndre, Phil (Supervisor), Eugene (Manager) and Xavier (Manager). I am very unhappy and disappointed by the way I've been treated by TFG, why do they block me from buying and not block me from paying. Then on the 26th August 2015 I was told that I owe R16000.00 on my Luella account however I am paying R2000.00 every month. Customer Service is not interested in my concern and my frustration is being ignored. The worst part of it call centre agents put you on hold when they cannot answer my questions.
