Telkom only after money even though no service

So in June I asked Telkom for uncapped internet they came to my residence and told me they need to first plant a new pole and put a new line to the house. I then said that this will not do and I will not be going ahead with the the internet and Telkom technician did not install anything. What Telkom Mossel Bay went and did was activate the internet and now Telkom is expecting me to pay R460 odd rand for a service I did not receive and wont cancel because they say I owe money. I have proof that the line was never installed and that I have contacted Telkom more than once to rectify this and since June Telkom is still not doing anything to rectify this. All Telkom can say is sorry you need to pay before we cancel anything and that this will now reflect on ITC and I will blacklisted. This is ridiculous from Telkom and there employees. Who can I speak to to rectify this as every Telkom employee I talk to does nothing about this.
