Dear Sir/Madam,

I am writing to express my dissatisfaction with the recent services provided by your company. I have encountered several issues that need to be addressed promptly.

Firstly, the quality of the translation work I have received has been consistently subpar. There have been numerous instances of incorrect grammar, inappropriate word choices, and even missing translations. As a professional translator, I expect a higher standard of accuracy and attention to detail.

Furthermore, the turnaround time for completing the translations has been excessively long. This not only causes delays in my own work but also reflects poorly on the efficiency of your company. Timely delivery is crucial in the translation industry, and I believe it is essential for your company to prioritize this aspect.

In addition, the lack of effective communication from your team has been frustrating. I have made several attempts to address the issues mentioned above, but my concerns have not been adequately acknowledged or resolved. It is important for a company to have open lines of communication and to promptly address customer feedback.

I trust that you will take my concerns seriously and take immediate action to rectify the issues. As a valued customer, I expect a higher level of service quality and professionalism from your company. I hope this matter can be resolved promptly and that future translations will meet the expected standards.

Thank you for your attention to this matter.

Yours faithfully,

[Your Name
