VDSL service not working

I have tried to upgrade from an ADSL to VDSL line with Telkom, but in more than two weeks they have been unable to connect me to the VDSL system. I am referred from one person to the next at call centers and support centers, but no one seems to know how to fit the system/problem.<br> <br> In the meantime I am paying for a service I do not receive and have spent more than 10 hours on the phone to call centers without being able to solve the problem.
