disgusting service

Went to the game store to purchase a pair of earnings which said R179 on d stand however on the earrings there was a tag states R149 so I asked the lady at the counter and she just I must pay R179 because that's what's on the stand so I asked for a manager and when she called the manager she said she is going for tea and she cant wait and was referred to a manager called collin who was even worst he was so arrogant and he thinks I'm a stupid and said that it was a bar code I told him that is the price and actually shown him what a bar code looks like and what a price looks like. In front of other cashiers and customer he made me look like a stupid so I said I wanna see his manager and he says go see in the front you can go ask them maybe they can help you but I'm telling you have to pay what it says on the stand I said no I'm not gonna pay R179 because the tag says R149 and he was so rude he actually walked away from me. Service like that I will never go back to game as I'm not dirt or uneducated to be treated by a so called manager. Game should actually send their staff for training. As customer service is no.1 without customers how will people like rude collin be employed.
