Telkom home fibre contract - ****, *******!

I signed up for a Telkom contract in the beginning of April, the fibre and router were installed but to date I have not been able to contact to the internet. After numerous calls to their technical department the issue is not resolved. Each agent I've spoken to has made it clear that they will NOT contact me back to resolve this issue unless I call them. I've made countless calls to them, they put you on the hold for long and then eventually cut the call... then they invoice you a ridiculous amount for unused services!!!! They have my banking details so they will ***** my money with no service monthly! I regret choosing telkom for home internet connectivity, what was I thinking going with a SOE anyway, at this point I want my contract cancelled as it's clear that they cannot serve me and I will go with an private service provider.
