How to Write Letter for slow Connection of internet.

Write a Letter to Manager for Slow Internet Connection.

Dear Manager,

         I would like to state that, my name is Maaz Ahmed from residence of Quetta city and I am using Internet connection of your company for past 6 months. But from recent 3 weeks your internet is getting slower day by day and I already complained a many times to your company but still I am facing this slower internet.
         It has caused so many problems, I couldn’t contact to my family and company due to its slow speed connection and all of my online work has stopped because I can’t send any emails through my computer due to this problem and it has bothered me so much.
If this problem wasn’t solved and continuous I would be left no choice but to switch to another network connection.

You’re truly: Maaz Ahmed
