Pathetic service to clients

I have been experiencing terrible problems with my land line and ADSL line for plus minus three years. I have to phone and lodge a complaint on a regular basis. The landline has been non operational for about a month now. The internet is intermittent and most times off line. I am unhappy with the situation as I have to pay alot of money a month for a service that hardly works. A land line is imperative in any household. I was told to buy my own piping, dig the trench myself so that new cables can be laid. This was done four or five months ago and no technician has been near the house to complete the task. I am at my wits end and am losing patience with the whole situation. It is high time companies take note of complaints and their staff attend to serious issues. I would like to think that my situation should take top priority and free service for at least six months as that is the length of time I have spent on the phone complaining
