Telkom useless - cant even install voice line

Telkom 'installed' voice line on Thursday (coincidentally so I can get an ADSL line though a third party so I can move away from their ******* Huwai ****le). The installers said all will be good to go in 30 min. Surprise surprise, it's not. I phoned on Thursday and spoke to Izal - she said the exchange is faulty and she would contact the installers and then contact me to let me know what is going on. She didn't call me back. On Friday I phoned again and spoke to Andiswe - she said the same thing and that she would phone me back - she didn't. On Monday I phoned again and asked for the supervisor - his name is Chandre - he said he would look into it and call me back - he didn't. I had a sneaky suspicion that this might happen, so I did ask him for his direct line which is *** but when I phoned it all I got was \the number does not exist". In the meantime I'm spending hundreds of rands topping up this kuk Telkom ****le that I have"
