Question

PLEASE HELP ASAP
How schould you start a letter for a complaint?
Write a letter of complaint. Follow the rules for a business letter,
and use the full-block style. The complaint may be about anything
you wish (such as malfunctioning equipment, poor building maintenance,
or disruptive noises from a nearby business). You can
base your letter on a true experience, or you can make up all the
details you need.

Answer 1

First I would introduce yourself and say your name and then say a greeting such as how are you or I'm sorry to bother you, and then I would list something about their being disruptive noises near by
