Re: Complaint Regarding Overcharged Bill on 02-02-20XX for Specific Products
Dear Sir/Madam,
I am Helen Watson from David Elson Road, LA. I visited your store in KE-Block, LA, on 02-02-20XX to purchase groceries, vegetables, and other food items. During my visit, I noticed a 30% discount on MsKays milk powder, StrongBox protein powder, and Milkyway porridge. I bought all three of these items to take advantage of the promotional offer.
When I checked out at cash counter No. 4, I was charged the original prices without applying the advertised 30% discount. I approached the cashier to resolve the issue, but he refused to offer any assistance. Not only did he refuse to help, but he also responded in a rude and offensive manner while discussing the pricing and overcharging matter.
Businesses are expected to operate with professionalism, supported by a competent team and a courteous approach toward customers.
I recently shopped at your store for the first time, and unfortunately, the experience did not meet my expectations. The impression I had formed from the outside was quite positive, but my visit significantly changed that perception. The overall shopping experience was disappointing, primarily due to a lack of cooperation from your staff.
I have enclosed an image of the bill, highlighting the disputed prices and the details of the products along with their respective rates. I kindly request a refund for the amount that was overcharged. If this issue is not resolved promptly, I may be compelled to file a formal complaint with the consumer court.
I would be grateful if you could investigate this matter and take appropriate steps to address your team’s behavior, including providing proper training to ensure they demonstrate professionalism when dealing with customers. I also recommend establishing a customer care office at each branch of your store to improve service and responsiveness.
My contact details are as follows: Email – [email], Phone – +[X]. I thank you in advance and hope for your full cooperation in this matter.
Regards
Helen Watson

Subject: Complaint Regarding Overcharged Electricity Bill and Unnotified Increase in Per Unit Rate
Dear Nadeem,
I am writing to bring to your attention the ongoing issue of overcharged electricity bills and the recent increase in charges without prior notification. I respectfully request a review of my complaint and a timely resolution to the matter.
I am a resident of New York City and have been living here for the past seven years. For the last two months, I have been experiencing overcharging on my electricity bills. I filed a complaint with the New York Electricity Supply Company and explained the entire matter to the Assistant Director of NY-ESC.
When I received my February electricity bill, I was shocked to see that it was three times higher than the usual amount. Sir, I am a bachelor living alone in a 200 sq. ft. apartment, and I find it hard to believe that such a small space could consume enough electricity to result in a bill of $860, including tax.
I was out of station for two weeks this month, and as a result, my electricity consumption was significantly lower, about half of the usual amount. I have attached images of my return ticket along with proof of my outstation stay. Additionally, I have enclosed electricity bills for the past six months to provide a clear picture of my regular consumption.
I kindly request that you investigate whether someone is illegally tapping into the general electricity connection or if there is an error in the system database. I would be grateful if you could look into this matter and resolve it at your earliest convenience. My contact details are as follows:
