四、投诉信的例文
Dear Sir/Madam,
I am writing to express my extreme dissatisfaction with the new TV I purchased from your store last week. I was very excited to bring it home only to find out that the screen was completely cracked. The TV was not even out of the box for more than two hours before the problem occurred.
I immediately called your customer service line and was told that I would receive a replacement TV in two business days. However, it has now been five days, and I have yet to receive the new TV or any notification about its status. I have attempted to reach out to your customer service department several times, but no one has been able to give me a clear answer about when the replacement TV will be shipped.
I believe that as a customer, I deserve better. I have already paid for the TV, and it is unacceptable that I have to wait this long for a replacement. I am requesting that you expedite the delivery of the new TV and provide me with a clear update about its status as soon as possible. If this issue is not resolved in a timely manner, I will be forced to escalate the matter to the Better Business Bureau.
I thank you in advance for your prompt attention to this matter and look forward to hearing back from you soon.
Sincerely,
[Your Name]
[Your Position]
