Cashier scam

Usually when people buy at super markets, it's usually to buy large number of commodities. Like cleaning supplies to kitchen groceries. Metro and Dmart are usually such places Yesterday I was at Dmart to buy house products and the cashier has billed 2,3 products which I didnt buy among close to 89 other things I brought. This was Dmart yelahanka, the cashier was soo rude...I mean I understand from morning they will be tried and try to be calm as much as possible with them but the do this disgusting job. I dont wanna do philanthropy I'm not that good of a person to let someone else take dove shampoos worth close to 500 on MY bill Anyone else experienced this before?and how to I report this will the dmartsupport mail actually reply
