Respected Concern,

I am writing this letter to inform you that I bought some groceries (Product type) from your store. One of the items was a 10kg bag of (Product type). The price mentioned at the counter was (Amount of money) but the time of billing the price mentioned on my bill was (Amount of money – Over Billing). I asked the cashier to look into it but he clearly refused by saying that it is not his duty and I am supposed to pay the increased amount. At that time I paid but now I am writing to you to look into it and refund the extra amount I had paid. (Show your actual problem and situation). I want a quick response from your end otherwise I have to take help from the consumer court. You cannot make the customer fool by doing such acts and you also need to update the system and teach your staff to be nice with the customer.

Please find attached list of items.  I am looking forward to your response. Thank you.

Yours sincerely,

Respected Sir,

I have sent you this letter to file a complaint regarding my overbilling of electricity (Service type). The past few months, I am receiving my electricity bill more than the average of whatever I have been receiving since I shifted to this house, which is more than 2 years. (Show your actual problem and situation).

I ignored the overbilling first time thinking that maybe this is due the increase in usage of units but next month the same thing happened even though I along my family were not at our place for about two weeks. I was sure there was some issue with the bill so I myself calculated the bill by multiplying the units with their price and was astonished to see the amount was not even the half of what I was paying. I have attached all my past bills and you can look into them yourself.

I request you to recalculate my bills and refund the extra amount I have been paying. For any further query please contact me. I would be thankful to you if you address this issue as soon as possible.

Best Regards;
