Vodacom won't cancel my contract

I have a data contract with Vodacom. In May 2015 Vodacom acknowledged that they cannot service the area I live in (Sunninghill Gardens) and that I am entitled to cancel the contract with no penalties. I was asked to contact the Cancellations department. After numerous calls and e-mails to Cancellations, I have been told repeatedly that the cancellation is still pending with no reason as to why it has not been resolved. In the meantime, Vodacom has continued to debit my cheque account for the contract.<br> <br> Refer to service request (A1-X52A-IW319G) and (S3-88R2D-D2IWO)
