Rude disappointing with KIT KAT CASH And Carry Pretoria West.

I went to buy cheese specifically Bonnita Gouda cheese .1.7 kg for R178 and when i got home I realized that the cheese was smelling detergents and I lost the receipt n my way home.After an hour I went back as the receipt and the kitkat sticker was still on.I complained and they told me that I can not get refund no replacement and they will call the police to come and remove me from the shop as i refused to leave the shop without my cheese and they smelled the cheese .I sat for 3 hours until they decided to assist me look for the receipt .The sore manager made allegations like what if the I stole the cheese and I told them that the shop was empty and it had cameras so it wouldn't be possible.He was so unhelpful till they decided to check the receipts and counter i used.I was assisted around 4:16 and the manager blatantly said that i should never buy cheese from them.Is this how Kitkat Pretoria west treat their customers?I didn't see any customers policy act in the shop.As a South african I got a right to be corrected not knowing which detergents was on the cheese this could have been fatal.No apologies from the store manager .He was very rude and unprofessional.
