Very bad service of Vodacom

I am fed up with Vodacom. I cancelled my fibre account in October. I have several reference numbers confirming that it was cancelled. Vodacom confirmed that my balance is R0. I keep on phoning different departments and every one tells me to phone someone else. No one can help me. Someone on their side decided that they didnt cancel it in October bu only December. Now I have been handed over to the attorneys. I urgently need someone to phone me from Vodacom. The ref nrs I gave them which they have mailed to me they are claiming is invalid. Vodacom is very very unhelpful. Vodacom is very unprofessional. We have been for an hour on the phone with no feedback. ***
