Telkom listing me inaccurately

I cancelled my landline and Wi-Fi services on the 25/06/2018 and only to find out that someone in Telkom has cancelled the order. Not only that on the 7/7/2018 the whole area's block had a fault. I logged a fault report and a technician came in September only. He realized that the problem was Telkom's technician that switched the lines around hence I never had internet since 7/7/2018. He said Telkom will need to pass a credit. I've been having endless problems and after the cancellation which was suppose happen 30 days later I still get bills and I have been listed on the credit bureau for something that isn't my fault. Now I'm struggling to get my credit report in order. They promised that they will clear the mark off my name but nothing is happening.
