Failed to refund within time specified

I went to Stuttafords on the 20.06.2015 to purchase, I swiped my card and it went through, a few min later we decided that we don't want it and went to customer service to do a refund and they said they need to do the reversal on the card that it was purchased with. which we agreed and the reversal was done, i asked the consultant when would the money reflect in my account which she said it will be in my account within 3 days. On Monday when i checked my account there was nothing , thinking that since it was it was the weekend that it could be working days, by Wednesday the 24.06.2015 the money still wasn't in my account. I called the Sandton branch and there was no answer, I called the head office they said they would get the relevant department to call me back which no one got back to me. i called them again and spoke to Christelle, she got someone to get back to me but I'm being given the run around now about the refund and say Ned-bank must refund me when i swiped my card at Stuttafords and I should wait 10 days for the refund. that is ridiculous as when i swiped my card the money was deducted immediately. they said they would speed up the process and still no money.
