Wrong pricing/Bad service

I went to look for a present for a party. I saw a nice gift went to pay but the price wasn't right the shelf shows R99. 10 but the product scanned R299. They didn't know what to do just looked at each other and then when trough al the product but there were no products of that price. If the workers can't do there work by removing prices if they put new products on that place it not my work. If I see that price that's what I want to pay. I will never buy from them again. There service are really bad. That's not how you treat your customers.
