A Complaint Letter

Dear Sir/Madam,

I am writing to express my dissatisfaction with the recent service I received from your company. Although I have been a regular customer for several years, I was deeply disappointed by the poor quality of the service provided last week.

To be specific, when I placed an order online on April 5th, I was informed that the product would arrive within three working days. However, it has already been more than ten days, and I have not received the item yet. Moreover, when I contacted your customer service, the representative was unhelpful and did not provide any clear solution.

Such a situation is not only inconvenient but also affects my trust in your company. I believe that every customer deserves timely and efficient service. Therefore, I would like to request a prompt resolution to this issue. Either a full refund or a replacement of the product would be acceptable.

I hope you can take this matter seriously and respond to me at your earliest convenience. I look forward to hearing from you soon.

Sincerely,

Li Ming
