Unaccetable service

On the 25th Feb we requested to have a line transferred as we were moving on the first. Firstly they didnt lodge it on the day and lodged i the following week. They then said is would take 7 to 14 working days which I dont have a problem with. On the 14th a technician came out to instal the line. He said there was a problem with the line from the box to the pole which another technician would have to sort out. He promised me my line would be connected by fri the 18th. Nothing happened. Then I got an sms someone would come out on the 23rd for an all day appointment to instal the line. We waited all day and no one pitched. Now I phoned them and they said the guy was too busy to come out he can only come again on the 4th. I have now waited a whole month for installation on an account that I am paying for. and it is costing me as I have to use my data now and not my wireless at home. I find this completely unacceptable
