Unhappy customer feeling **** to.

I appreciate the people working at the tills, however SPAR had some items displayed at the door which were on special but when I looked at my till slip once I had arrived at my place-of-stay, I had been charged normal price. That was bad enough, but I bought 4 chocolates which were on special, at R6.99 normal price with a R2 discount, but on my receipt I was charged ***R10,09***!?

10,09-6,99=3,10... how can you charge me R3,10 more than the listed price?? Especially when it is on special, I feel like that is a double lie.
