Sh*t service

I have a 24 month ADSL contract with Telkom ,but since the beginning of August there has been a fault with my line so I've been sitting without WiFi for the past 6 weeks, the fault has been reported many times and escalated , they keep telling me the" technician is busy on the line" and whats worse is now they expect me to pay for the service I haven't received,yet they can't even tell me when my line will be back on or if it will be back on , how can they expect me to pay for something I haven't received, I have a business that runs on WiFi , I have been wasting a lot of money on data that I couldve saved if Telkom just plays their part , it's been 6 weeks and I phone every day yet no one can tell me anything and the manager doesn't want to speak to me every time I ask for him
