Checkers is a ****

Today 28/01/25 I went to Checkers Northdend Pinetown to do my groceries. I ended up buying the Home Discovery Diamond 3 piece roaster set. The teller told me that if I want 3 piece I must pay R229 x3 because each item has its own price. I asked him how was that possible because in the shelf it says 3 piece. He made me look like I was trying to **** them. Upon arriving at home I decided to check the set online and I saw that I was actually right and I payed the full price but other items were removed. Even on the tax invoice it says 3pc I'm not happy about this 😕
