Telkoms terrible service!

Its been 4 years since applying for an adsl line from Telkom, which we never received but now been blacklisted for something that we were told on numerous occasions is resolved! The bill has changed many times as well. Basically i would not recommend Telkom to anyone as they have ****** many people and blacklisted quite a few, claiming money they are not entitled to! I have also previously reported it on here and was contacted to also be told its resolved!
