Subject: Complaint Regarding Service at [Company Name]

Dear Customer Service Team,

I am writing to express my dissatisfaction with the recent service I received at your store located at [Address] on [Date]. As a regular customer, I have always had a positive experience with your company, but this particular visit left me quite disappointed.

On the day of my visit, I came in looking for assistance with a product I had purchased a few weeks ago. Unfortunately, the staff I spoke with was not very helpful and seemed uninterested in resolving my issue. I waited for over 20 minutes just to be directed to another employee, who then informed me that they were unable to assist me without further information.

This lack of support not only caused unnecessary delays but also made me feel undervalued as a customer. I believe that all customers deserve prompt and professional assistance, regardless of the situation.

I would appreciate it if you could look into this matter and provide me with a proper resolution. I hope to hear from you soon so we can find a satisfactory solution.

Thank you for your attention to this issue.

Sincerely,

[Your Full Name]

[Your Contact Information]
