New Line not installed

I app**** for a new Telkom line on the 1st of February. Telkom has scheduled 3 appointments to install my line but has not pitched up. I have been to the Telkom store 3 times already but they say there's nothing they can do. Not having a phone and adsl is costing me on a daily basis. How can Telkom continue to provide their customers with such poor service. I think it's time I look at the competition as I cannot deal with the level of incompetence.
