iStore Refund Nightmare

I purchased an Apple TV for R3600 from iStore in Sandton Drive on 6 January, and promptly returned it to the Mall of Africa store (which is closest to me) on the same day. The manager advised that my refund may take up to 6 months to reflect, unless I produced a credit card. I did not want to use my credit card as it is only for emergencies, so I produced my debit card instead. I then followed up with the manager, Gordon, on the 9th of January and received no response. I contacted him again on the 13th and was advised that the refund would reflect the following day as it was released from their bank. On the 16th I followed up again and was advised by another manager, Paul, at the mall of Africa branch that the refund would instead reflect in my bank account on the 20th. He also advised that if the customer doesn’t want to use a credit card for the refund, or doesn’t have one, he insists that an EFT payment is done instead - this wasn’t the case with my refund. I followed up again on the 21st as I hadn’t received my refund yet and was assured that the funds would reflect by COB on the 21st. I am still waiting. The fact that a refund takes this long is utterly unacceptable, not to mention the fact that I have been **** to since I queried the refund.
