Respected
Sir / Madam,
I would like to draw your kind attention on
the fact that the postman of our area is very irregular in his duties. He does
not deliver the letters regularly and properly. He throws the letters
carelessly. He gives our letters to the wrong persons. Sometimes he misbehaves
the people.
People face
many difficulties because of his misbehavior. A student missed to go in his
interview because he got his interview call after the date of the interview.
Hence I
request you to take necessary actions against the postman so that people may
get proper and good services.
Thanking
you in anticipation
Yours
Faithfully
