Do not switch over to wireless line

I was contacted approximately a month ago by Telkom to switch my landline to a wireless system. I agreed and received my new cable-less (not cord-less or wire-less) phone in a week. I plugged and connected same. Then few days later my land line got disconnected. I was told my new phone will be connected within 5 days of the disconnection. 3 weeks later I am still waiting for that connection despite going twice to the Telkom stores in Gateway and Cresta. Tried also contacting Telkom but you end up sitting on your cellphone for over an hour to connect to someone at a call centre then its the wrong department and then you star all over again. I regret agreeing to the change over as now I dont have a cordless phone at home and I dont have an extension at home to use - neither do I have a line that I can use - but I am being billed for this. Telkom staff attitude is 'blaze' to say the least - they really dont care about the customer. They are the worst service provider in the World - they know it, as I have told them several times - they just dont care. Their 72 hours turn around is more like 72 days
