Afrihost DSL issue

Afrihost handled the dsl part of my Telkom fixed line. Internet service went down on 26 October. After weeks of phonecalls, emails, etc. I decided to cancel as nothing was getting fixed and no solutions of alternatives were offered to me, a paying customer. Please note that I still had to pay full price for this nonexistent service. I received an invoice from Telkom today for the same line. Telkom is unable to cancel the line because Afrihost apparently has not yet released it. This means that I have been paying and will keep on paying for months for LITERALLY NOTHING. I have contacted Afrihost AGAIN but I am still waiting for a response. I am trying to get to the bottom of this, but I'm not getting anywhere.
