Complaint Letter About Bad Customer Service

I am writing to express my deep dissatisfaction with the recent experience I had with your customer service team. On [Date], I contacted your support department regarding [specific issue or product/service], and the service I received was far below the standard I expected.

To start with, the representative I spoke with, [Representative's Name], was not only unhelpful but also displayed a lack of professionalism. Despite explaining my issue clearly, the responses I received were evasive and did not address my concerns. This left me feeling frustrated and undervalued as a customer.

Moreover, the promised resolution time was not met. I was assured that my issue would be resolved within [time frame], but as of today, I have yet to receive any update or solution. This delay is unacceptable and reflects poorly on your company's commitment to customer satisfaction.

In addition, when I followed up on the status of my complaint, the response was dismissive and lacked any substantial information. I was met with long hold times and unreturned calls, further aggravating my frustration. This level of service is neither courteous nor efficient and has caused significant inconvenience on my part.

Furthermore, I was promised a [specific compensation or benefit] as an apology for the inconvenience caused. However, this offer was never fulfilled, which adds to the overall disappointment with your service.

To conclude, I am requesting a formal apology and an explanation for the poor service I received. Additionally, I expect that my issue be resolved promptly and that steps be taken to prevent such incidents in the future. Please address this matter urgently to restore my confidence in your company.

I look forward to your prompt response.

Sincerely, [Your Name] [Your Contact Information]
