I will try to edit it:
"Last month, April' 09, I stayed at you hotel and the weather turned bad unexpectedly. It was raining and there was no proper heating in my room.
Those days I suffered a great deal because it got unusually cold, the heater wasn't working well and the roof of my room was leaking rain water. So I complained at your service desk, but they just came and looked at the heater and roof and said, "We'll be working on it", but nothing was done. Then I asked them to change my room but unfortunately there weren't any vacant rooms available at that time. I spent 2 days and 1 night in very poor conditions and due to this I came down with a fever. I was sick when I left your hotel and the next day I was unable to go to work, which was very important to me.
I hope you will pay attention to this letter and try to fix your service center and renovate your establishment. Your hotel is in the center of the city and is very convenient. Next time, I would like to stay at your hotel in hopes that you will take better care of your customers.
This should be fairly correct. Also, you listed July'09, which is next month. If it was a month ago, it was probably April'09. I hope this helps!
