Unwanted Warranty Charge: Complaint Regarding Unethical Sales Practices at [Store Name]

Dear Mr. Simpson,

I am writing to express my disappointment and frustration with the service I received from your salespeople. During my recent purchase of a mobile phone at your store, I explicitly stated that I did not want a one-year extended service warranty. However, to my surprise, I found that the warranty charge was included on my credit card statement this month.

I feel cheated and misled by your salesperson who charged me for a service that I did not authorize. Needless to say, I refuse to pay this charge. As a customer, I expect to be treated with honesty and transparency, and this experience has left a bad taste in my mouth.

I urge you to take immediate action to rectify this situation. If you cannot ensure that your salespeople uphold ethical business practices, it calls into question your ability to manage your store effectively. I had planned to return to your store this month to look at your electric fans, but I will now take my business elsewhere.

I hope that you will address this issue promptly and take steps to ensure that your customers do not have similar experiences in the future. Unless this matter is resolved satisfactorily, I will not be returning to your store again.

Sincerely,

Brent Zheng
