DISCHEM POINTS NOT AVAILBLE

I was at Dischem Carnival mall on the 27th October, and planned on using my accumulated points. At time of payment, I advised the cashier, I would like to use my points. At time of swiping, there was a technical problem, I had to pay cash, which I was not happy to do as I was low on funds, however needed the items so I paid. Today 07/12, I'm feeling unwell and purchase some vitamins for myself and decide I will use my points as a single income home, every cent matters, and spare cash is a luxury. I advise the cashier, I will be using my points only to see that I have 92 points. I go to customer service who looks into my profile and advises that the points of 335, went off on the 27 October, I also show her my bank account which reflects the payment I made on the 27 October from my bank account. She calls Dischem Carnival mall, they will reverse the transaction it will take about 3 days. Yet again I need to use cash, R 494. I would like to know from Dischem, how am i going to be compensated, at all times I was inconvenienced for a few hundred rands, this is money that I would need at some point in the month. If I had the luxuries of shopping elsewhere and using cash, I would have done so. Please provide feedback.
