Very bad service from manager and assistance manager

I just had very bad from PicknPay Mulbarton. I had taken a Little Bee honey 1g which was priced 35.99 on the shelves. As I get to the pay point I was told it's R144.99 and the teller lady had said when this happens customers are given the item at that amount. When assistance manager was called she had said I'm going to manager and as she came back she said manager said I can't take it at that amount. What I didn't appreciate manager and assistance didn't bother to apologize or being polite to assist me. The ladies who notice the mistake said to me they do give other customers the items at that amount because it's stores faults not mine. I'm asking myself the service I was given is because I was undermined or taken to advantage as for my race. Service was very poor from manager..
