I bought all my groceries from big bazaar as there is large number of variety available in these stores. I never checked checked price of items and go for the total bill amount.
For the last few months I am started checking MRP and the amount on the bill and found that in few items they charged me above MRP and the price they offered on various product is not the same printed on the bill. When I next time I complained about this they didn’t cleared that and started arguing in rude manner.
