Contract Cancellation

I cancelled a contract that was due for renewal in Aug/Sep. I was constantly being contacted to renew and I refused. The contract was supposed to expire end Nov 2014. It is recorded on Vodacom's system as cancelled and now on pre-paid but I'm still being billed for the contract. I've contacted Vodacom on numerous occasions with no success! It is now Feb 2015 and I'm still being billed for a contract that expired end of Nov with a refusal to reverse any billing done over this period. <br> With every call I've been told that there is no cancellation recorded and the person helping then does the cancellation.. Each person ask me if i have a reference but i never get a reference no.<br> What assurance do I have that anyone knows what they are doing???<br> <br> People I've spoken to:<br> Bonga - 5 Jan 2015 - 1:15 pm<br> Sibo dlamini - Cancellations - Bonga - \prepaid end November Request a refund for the bill.<br> Cancellation was loaded but there is a glitch in their system"<br> You will receive a message to switch off the phone for 24 hrs - reference\""<br> 29 Jan 2015 Sharlotte Mavunda 21 jan migration escalated to IT\"" <br> Christina Dyosini - 4 Feb 2015 3:00pm"""
