No receipts at KFC Hammanskraal

On the 04th October 2015 I bought food at Hammanskraal KFC and they did not give me a receipt despite my request. I was told they are doing stock take, therefore they could not issue a receipt, instead they wrote on a piece of paper that I had a bought a meal from them after I refused to go without a receipt. On the 11th October 2015, I went to the same store and I still did not get a receipt. They also wrote me a note on a piece of paper. None of these were carbon copied. On the 12th October 2015 I logged a call with the customer care line, and the matter was referred to a lady called Joyce who claimed to be the store manager and we did not reach a consensus and she promised to call me back. A week later, I called the customer center again and I was promised to be called back. Since then I have never received a call from any of the above.
