You were charged for items which you have not purchased at the local grocery shop.
Sample Answer
Dear Manager, Yesterday, I came for grocery shopping in your store. When I checked the bill after reaching home, I found that some items were added to the bill, but I didn't buy them. I bought two family packs of bread, two packets of cookies(the small one), one bottle of 1litre coke, half kg onions, and 1 kg potatoes. But when I rechecked the bill, three packets of noodles and some snacks were also added. I come to your store almost every month, and this sort of thing has never happened before, but I think this was by mistake as there were many people present at the cash counter yesterday and there was only one person who was handling all the billing. I have some urgent work today so that I will come to the store tomorrow in the evening. I was hoping you could look into the matter and refund the money deducted for something I never got. Kind Regards. Mike.
