Telkom - the same as talking to a wall

Our (whole area) Telkom lines stopped working mid February 2018. The lines were reported a couple of times. The technician working in our area keeps on telling us that Telkom head office refuses to send the parts that is needed to fix the problem. The last message from the technician is that the lines will not be fixed because of old technology. That is fine but then stop billing us for services!. I have logged numerous disputes to reverse the service charges but they keep on billing ! After many attempts to try and talk to someone about it (nobody at Telkom knows what's going on and nobody can help you) the standard answer is " log a fault". We decided to cancel the line and service. What a mission, Telkom makes its nearly impossible to cancel. Nobody at any call centre can assist - after many attempts we found a nice lady that told us the only way to cancel is to do it via the old internet portal. We have cancelled our line. We still have many disputed logged for the reversal of the monthly billing for services. Of course NO feedback on these ... instead we got a message that we have been handed over for collection of the outstanding money for NO SERVICE from Telkom. Very happy that we cancelled - Its was like talking to a wall where nobody is willing to assist. But of course Telkom is very fast to hand over or blacklist. At this stage we are just thinking of paying the money that was billed for NO SERVICE just to be rid of Telkom.
