Pathetic service

Yoh the run around you do to get service is pathetic, first it was for a second line, which I was told it won't be possible cos my area is not covered, even pathetic was the fact that I am already a customer so my area is not covered how? Seems to me that your staff is just out to frustrate the living shts out of clients. None the less, that was sorted after months of back and forth. ***as now I am struggling to upgrade to a higher speed, its been months, like what the hell, come on guys ...acc no ***...can someone please assist me with my upgrade asseblief
