Reliance Fresh — abusive words by reliance fresh staff

We went to reliance fresh manikonda which is opposite to food bazar.. We took our son also and by mistake my son placed a little urad dal with wheet... It was not a loss at all. But the store manager shouted very rudly to the child and also to me that i need to bill the entire thing... Though i beared his shouting and arrogant words to my child i beared it... Billing is done and again that person stood near security and he checked the bill and told that u have not billed and u cant leave without going because he got a loss... My husband asked to show the proof of the loss he went.. But he did not find any thing and again strted to abuse... I kindly request you to make your staffs learn manners and politness and especially should give a training how to talk properly
