UGLY service from Telkom

Its just been hell dealing with Telkom for the past 4 months. We were with no internet since August and have been reporting the matter almost every week but Telkom would still bill us for the service they were not providing. We have seen more than 6 different Technician by our office but still nothing changed with our internet, call centre consultants suck, you speak to different people and they all tell you different things that never worked and by the way this ADSL is for a business not an individual or for home use. I salute one technician by the name of Willem who only came once on Friday and managed to figure out the problem and indeed he worked tirelessly to have our ADSL line back on again. He came again this morning to make a follow up of the job he did. Telkom just need competition to up their game, its so frustrating dealing with them. They still haven't credited us for all the months they charged us when we didn't have internet. Telkom please credit us all the money you billed us for nothing.
