No Internet Access for WiFi and mobile networks in my area

Its been over 5 months placing a complaint regarding the Internet network affecting our area therefor making our wifi not tl work at all. Today marks 1 week since they said their technicians will call and attend to the problem. I don't see why i have to continue paying for wifi services that haven't been working for the past 5 months and bear in mind this is my 4th year using their WiFi. Mind this is the same as our mobile devices whenever we are home it just goes to no service!
