Disappointed with telkom customer service

I have been a loyal and well paying customer to telkom for years now, and I have been experiencing endless problems on my side. My home telephone has been down for months now, telkom went around replacing everyone's landlines but for some reason left my home out so I decided to change it myself once done it only worked for a few days and then went faulty again I have logged complaints and tried to sort it out on my own nothing has worked now my internet has been down for over a month and everytime I phone them it's sorted out for a day and it's faulty again. I called them 3 days ago and I was advised it was a problem on their side and someone would come to check it out but 3 days later nothing has happened and no one has come through. But my bills are paid and Iam sitting without a phone or internet.
