cancellation

I phoned on the 15th Oct and went through to the cancellations on the computer self help service, i cancelled my contract for it to end on the 3rd Nov 2015. I then phoned cancellations on the 16 Oct to confirm cancellation and they did. I then phoned on the 29th Oct 2015 just to make sure, and once again confirmed! Today is the 3rd and its not cancelled. When i phoned cancellations nothing was loaded. Once again fantastic service from Vodacom! The person told me that im still going to pay my contract at the end of Nov which will be the 25th month! I just refuse! I hate vodacom. Ive always had bad service!! You would think after having more than 10 years with them they would treat you better... well im done now!!
