Dear sir with due respect, i am writing this letter to inform you that my home wi-fi connection is disturbed from last few weeks .I am facing trouble as i am having most of work is done online and for that i need a proper internet connection . In my modem last server light is not working proper, we raise compiaint to omantel they says it was the problem of modem .Today i buy new modem and set, now also i am facing same problem. Computer operator says its the problem of line only not modem . I have already made a complaint but no one took any action upon it .I request you again to send someone from your office to check my connection.I expect a quick response as satisfying your customers should be your first priority. Thanks
