I was at till served by Bulelani

I was at till served by Bulelani. I was buying the easter eggs and the price was different from the one on the till. I went with Bulelani to confirm the price after that she told the Supervisor that the price was on top of the easter eggs and was different from the ones on the till. The Supervisor said no this is not the price and she cancelled everything just like that as if it was my fault. I left those easter eggs there. I'm not happy the way they handled the matter. They don't know how to treat a customer. I am not happy at all
