范例

以下是一封投诉信的范例：

Dear Sir/Madam,

I am writing to express my dissatisfaction with the recent product I purchased from your company. On July 1st, I bought a microwave oven (model X) from your store, and it stopped working after only two weeks of use.

I am extremely disappointed with the poor quality of the product, as I expected it to last much longer. I have attached the receipt as proof of purchase and the warranty that came with the product. I demand either a refund or a replacement of the faulty microwave oven. Furthermore, I would appreciate it if you could arrange for the defective item to be picked up at my convenience.

I have been a loyal customer of your company for many years, and this is the first time I have encountered such an issue. Therefore, I hope you can understand my frustration and take immediate action to resolve this matter.

I kindly request a prompt response to this letter and a resolution to the problem within 10 business days. Should I not receive a satisfactory reply, I will have no choice but to consider taking legal action or sharing my negative experience on social media platforms.

Thank you for your attention to this matter. I look forward to hearing from you soon.

Sincerely,

[Your Name]

[Your Contact Information]
