Returns Policy need to be revised

Last night at about 17:20 I visited Ackerman’s in Ottery Hypermarket. I spoke Cashier Tamryn Hendricks and showed her a Navy Tango Pump shoe that I bought at the same store less than 2 months previously value R99.95. She called her Manager called Chevonne who advised that I need to have a receipt to change the shoe. I told her that I do not have a receipt that had I known that the shoe wouldn’t last 2 months that I would have kept the receipt. She said that she can’t return my money that I could take something else to the value. While I was looking at other shoes I realized that I didn’t have my wallet with me as I had gone to Ackerman’s straight from Gym. I went back to my car to fetch my wallet as the shoe I would have taken in its place was R49.99 more than I paid for the shoe that was broken. Upon my return, Tamryn Hendricks advised that the shoe is currently on special that she can only refund the sale price of the shoe. I then advised her that when I purchased the shoes it was not on special and although they still had the same shoe in store I wasn’t going to take the same shoe as the sole is inferior. My gripe is, refund the full value not the sale price. It’s not about the money, it’s about the principle of the matter. How many times do they not do this to other people? Ackerman’s buys in cheap shoes from China and then they just put their own label on it. I’m logging this complaint on Hello Peter and next I’m reporting Ackerman’s to the office of the Consumer Protector.
