Dear Manager,

I'm sending you this email to tell you about a problem I had at your grocery store recently. When I got the bill, I saw that I was charged for a few things that I hadn't bought.

I bought a carton of milk, a loaf of bread, a pack of butter, a dozen eggs, and a few different kinds of vegetables. But I was surprised to see that I was also charged for a pack of cookies and a bottle of soda that I didn't buy.

I kindly ask you to do what needs to be done to fix this billing mistake. I'd like you to give me back the money I paid for the cookies and soda. I would also suggest that your staff be more careful when billing so that these kinds of mistakes don't happen again.

I like your store and the high-quality items you sell. So, I hope this problem gets fixed as soon as possible so I can keep coming back as a loyal customer. Thank you for taking the time to read this.

Sincerely,

ABC
