Unacceptable customer service

It's been more than a year now since I requested Telkom to move my ADSL line. They said that they are unable to provide me with ADSL in the area where I moved to because of infrastructure. I asked them to just supply me with a landline as I needed my fax to work. Until today I haven't received any call from Telkom and I'm still without a landline. I logged numerous complaints and still no feedback. Just got a sms again saying that I owe R928....for a service that I do not have. Sort out your customer service because it's non-existing!!
