Never sign anything with DSL and Telkom

I have always been weary of signing up with Telkom. It's well founded. For the first few months things were okay but then they just went totally down hill. 24 months later and I have searched for ways to end my contract. Begged DSL who are the *********s I signed up through to cancel the contract, been online to try cancel the contract even left comments on social media letting people know how terrible the service is and how impossible they make it to cancel the contract. Got a call after the last complaint saying it's cancelled only to hear from a sales person yesterday that it's not. What a nightmare.
