Incorrect Bedset delivered

My wife has a account with homechoice, she ordered a bed set with head board. We have received the incorrect item. My wife called the call center three times, each time she used up 30 rands airtime. Spoke to Lisa, Ashton and Linka. Till now no one has called back nor has anyone come to check the incorrect item. I have also called the called center several times, because it is not my account they refused to help, I also left my wife details for the agents to call back, they said that they are busy and will call after lunch. It has been over a week and no one has called. This is real poor service as we order and item get the incorrect one delivered, still have to call several times wasting money on airtime. The agents honestly do not value customer satisfaction.!!!!
