Card Refund didn't go through

On the 2nd May 2015 I went to Homemark in East Rand Mall, and purchased the Aluma Wallet for R149.95 using a Capitec MasterCard. A little while after, I realised the product wasn't as advertised (I was told 15 card can fit in it, but I couldn't even fit my 10 cards in it then it didn't want to close). The lady begrudgingly did the refund, giving me a correction slip, and telling me that the funds will be back in my account within 2-4 working days.<br> Today is the 11th. Homemark took my money, didn't refund it.<br> Homemark took the slip, had me write my number and nature of the return on the back and now they don't want to rectify the refund because I don't have a slip. (BUT THEY TOOK THE SLIP) And they say the correction slip isn't valid. (BUT THEY GAVE IT TO ME) Now I'm R149.95 short and Homemark isn't willing to help me at all.<br> Very upset.
