Vodacom ******ing Money from me

I require assistance. <br> Vodacom cancelled my contract and deleted my number from their network after them removing my banking details from their system. I reconfirmed the details with them which the request was added on their system to reload my details, but as they confirmed was never done and the deleted my number.<br> 3 months ago Vodacom debited my account, and when I called them as I have done during the year there was no outstanding money on my account, ID or name.<br> A debt collection company contacted me and is trying to ****** R5200 out of me which I am expected to pay for services up until 2017. After a few arguments they finally gave me my contract which states it's a 24 months contract and was signed in 2013, Vodacom cancelled it a month before ending.<br> I have asked that if I have to pay they re-instate my service, but no one is getting back to me apart from the debt collection agency who is taking out a court order apparently against me.<br> The debt collection agency confirmed that my contract was indeed cancelled by Vodacom, but I still am required to pay for services up until 2017.<br> I am not getting any response from their legal department or any other department
