Disappointed customer

I made an online purchase for twinsaver toilet rolls. It was advertised 4 packs of 18 for R189, I purchased 3 quantities which amounted to R567. This purchased was on the 31st October 2025. On the 5th November makro had cancelled the order without an explanation and refunded the payment. This is quiet misleading when advertising online as consumers should pay for what was advertised regardless if there was a mistake made on yourl end.
