This is what I came up with. But I am not sure how correct I am.
You might want to get a second opinion
Last week, during the telephone conversation I had with Mr. A of your department I was informed of a new electronic mounted fan (the previous one was stolen three months ago) having been set to be installed, on which a metal combination padlock was suggested to be attached, which would cost $700. It has been months that our park toilet has been without an electronic fan, which has become an increasing source of public discontent
Please keep me informed of your work progress as soon as possible.
Thank you for your cooperation.
