A Letter of Complaint

Dear Sir or Madam,

I am writing to express my dissatisfaction regarding the recent experience I had with your service. On [specific date], I purchased a product from your store located at [store location]. Unfortunately, the item did not meet the quality standards that I expected and experienced issues almost immediately after use.

Upon inspection, it became evident that the product was defective. For instance, [describe specific problem, e.g., "the screen flickered continuously" or "the battery did not charge properly"]. This issue has caused significant inconvenience, as the product is essential for my daily needs.

I have attempted to resolve this matter by contacting your customer service team on [date of contact] via [method of contact, e.g., phone or email]. However, the response I received was unsatisfactory and did not address my concerns adequately. It seems that no proper action has been taken to rectify the situation.

In light of these circumstances, I would like to request a full refund for the defective product. Alternatively, if possible, I would appreciate it if you could provide me with a replacement unit that functions correctly. I believe this is a reasonable expectation given the nature of the problem and the fact that I purchased the item recently.

I trust that you will take immediate steps to address this matter and ensure that such issues do not occur in the future. Your prompt attention to this complaint will be greatly appreciated.

Thank you for your understanding and cooperation. I look forward to your response.

Yours sincerely,
