Letter of complaint

Dear Mr Smith,

I am writing to complain about the new burglar alarm you have recently installed at your our home.

Firstly, it seems to me extremely disturbing that the alarm suddenly turned itself on during the night, while my entire family and myself I were sleeping asleep. This fact (try also to avoid using fact fact twice in 1 sentence - repetition) has happened at least three times in spite of the fact that I informed your spouse that the alarm was not working properly two weeks ago. In my view, it is as extremely disruptive such to as my family as it is to the rest of the neighbourhood.

Secondly In the second place, I have repeatedly tried to talk to you in order to resolve this matter. However, it has been impossible due to the fact that you are never available to meet me.

For all that these reasons, I am requesting either you repair the burglar alarm or you remove it definitely (I think you mean indefinitely).

Please, contact me within the next few days to ensure these steps have been taken.

Thank you for your prompt attention to this matter.

Yours sincerely (remove comma)

Inma L. M.
