Complaint, bad service.

Vodacom cancellations Department service utterly poor. I have been struggling for almost a year to get a contract removed from my account. I do not even have a sim card for this and I never wanted this. Everytime I call to raise this, Im being passed around and then told this will be refered to a back office who will then contact me. This never happens. Still nothing was done. I need contract on number *** cancelled today. My contact number is ***.
