Vodacom Fibre the worst you can get

I uave given Vodacom fibrea chance and it was a mistake. They have rep**** on Hellopeter that they would be in contact. Nothing has happened. I am trying desperately to cancel their service because Im paying R700 for a 10/10 line where as Other service providers are offering 35/25 line for R639. As you can see Vodacom is not responding after even logging the line cancelation SR***. I can not apply for a new service provider as long as they hang on to the fibre line. Its realy bad bad.

Vodacom what must I do????
