****** of my refund money

Hi I would like to lay a complaint against a Mr Price store in Kolonnade Pretoria North, cashier and their supervisors. I went to this store today returning an item worth R199.99. I request for my refund in cash from the cashier (Magdeline Mndmuzulwana) and supervisors (Tiego Mathekga and Kgomotso Maheso). They requested to see my card before they can refund my money because they don't do cash if the purchase was done using a card. They checked my card asked me to put the card into the pos machine so they can process the refund amount after I asked them why am I now putting my card into the machine as though am buying from the store. They told me it's procedure after giving me an attitude. I put my pin into the machine as they requested They took back the item after confirming with the slip I gave them. I asked them how long is it before the money goes back into my account they responded uncaringly and asking around and somehow murmuring with their supervisors that they e tdon't know. Before I made it outside the door of this storeI received a bank notification on my phone that the amount of R199.99 was deducted from my account. I went back to the store showed this to one of the supervisor who was during this transaction and they just didn't want to own up Tiego the supervisor instead argued with me and irritatingly said I will wait for the manager whom she was not sure when she was coming back. At this point I was angry because they now double charged me by taking R199.99 twice from me for an item I don't even have anymore. Their manager (Kgomotso Maheso) came to check what happened and the slips processed and showed them that they actually did double charged me instead of refunding my account. The manager phoned store manager (Mac Malatji)for a solution he insisted on system error and refused to give me my money back which I explained to him that the money they now took I had an urgent use for. He told me that I should wait for their systems before I can get the refund money plus the money they took from my card. I explained to him I cannot drive again for a refund to the store which he should be paying me now worse part now that they have their item plus the additional amount from me! He still refused to pay me money back together with his staff. Am not happy with the way things went with the store and my transaction. They took my money twice for no reason and without showing any remorse but justifying their actions everytime I spoke to them and after I gave them back their item with the slip as proof!! They gave me and bad attitude after *****ing my money and refused to return it!! I need my money from these people and their store!!!
