Billing for services incorrectly

After dozens of phone calls from Telkom sales division in September 2015 I was eventually convinced to upgrade from ADSL to the latest technology in our area, Fibre Optics. I was promised that it would only cost me R200.00 per month more than the ADSL line. The cost would go from R499.00 to R699.00 per month. This all happened in September 2015 and Telkom have been billing me for the ADSL line, a landline number as well as the Fibre Optics line. I have spent hours on the phone to their \Customer Support\" number, what a joke. I have also stood in queues for hours trying to sort out their errors. Both of these contact areas are a joke beyond belief. You are promised that the problem will be sorted out or that I will be contacted within 24 hours. Nothing ever happens. I have been blacklisted and am getting Final demand letters. Telkom, your service stinks. I will never use you ever again after you sort out your problem created by yourself. I am disgusted."
