Pathetic service

Our company has requested for a 4meg ADSL line in 2012, the service and operation was good up till about 4 weeks ago. We experienced and internet connection problem on the line, the call was logged *** on the 8/07/2015. With the call centre agent on the line they mentioned to me that our 10meg line is operating fine. To my surprise I said to the agent that we have an 4meg line and not a 10meg line. The feedback was that we are being billed for a 10meg line since the installation, how is that for ***** overcharging clients for something they don't even have. So a launched an dispute *** as this is nothing other than *****ing from clients, since the call logged we have experienced numerous problems with the line. The *** was closed as technician reported that the problem was resolved clearly not as the line is still faulty. I phoned in again regarding the faulty line and reported and escalation call *** on the 15/07/2015 hoping that this will help still nothing. On the 16/07/2015 *** I reported the fault again as the problem was not resolved. I phoned Telkom again *** referring back to the previous calls logged.
