问题解答：
To whom it may concern:
I spent my holiday at your hotel and I was hoping that it would be a pleasant stay. However, I found that the services provided in this hotel is not at an acceptable level. The receptions cannot understand my need and provide service efficiently. I was really disappointed. I hope that your hotel can spend more time to improve your employees and service quality. When I return to this place next time for my vacation, I wish that everything will be improved and I can have a good time during my stay.
Thank you for spending your time and reading this letter.
Yours truly,
(your name)
