Letters / You rent a house through an agency. The heating system has stopped working - letter [3]

Dear Mr. Anura,
I am Chinthaka Narangoda who is from rented house block no 3 on Riversend street. We met each other when signing the rental agreement at your office two months ago. I live here with me my wife and son. Since my son is quite young. He needs a comfortable environment and you know that these days are quite cool. We are felling uncomfortable because the heating system is out of order.

So that I decided to writing this letter to complain about heating system of my house, which has been out of order since last week. Although I gave call to your repairing section as soon as it was stop working. But unfortunately so far they have not replied me on this regards. But I am really unsatisfied with it.

I tried several times to directly contact you. But somehow I could to do it. That is why I decided to write you. I hope that you will give propriety to attend on this matter as I made a complaint last week.

In my point of view it is better to replace new one rather than repair old one because it is quite old
I am looking forward to hearing from you
Yours Sincerely
Chinthaka.
