Utterly Horrible Service

The item I was purchasing was of a certain price, when I went to the till to pay it was a different pricing. Told them I'm to pay for the price displayed, they called the Manager by the name Tumiso. He was extremely rude, bad service, bad attitude. Tell me why Checkers stuff would have proper manners if their manager doesn't know nor practice customers service. The way the whole thing was handled I ended up leaving as we have already wasted so much time with him not being productive and useful. It wasn't my fault that they didn't label their items correctly. You need to deal with him, take him to customer service class because these no way a Manager could act like that
