Persuasive Letter Front Office Essay

I am writing this letter because the lights in our office have blown out, and we were told that there would be someone out to help us replace it on December 3rd. Except no one has come and it get's quite dark in the office with only half of the lights.
I've called the front office mulitple times and have been told the same thing over, and over that someone will come up and replace the lights.
The repair is needed rather urgent since half of the office can't get any work done. So if you could arrange an electrician out to come fix the lights immediately.
