Cancellation Request not complete after 1 week

Hi,<br> <br> My contract expired on 21 October 2015. I was told by both MTN staff at Sandton and MTN Direct that I can call the day after and request a cancellation of my contract and move to prepaid - it should take 24 hrs. I called ot request this - after a week my contract was still active. Calling a second time, they said that the cancellation/conversion request was sent to the wrong email address and they resent it properly. By 2 November, it was still active. I called and a re-request was sent and was told it will happen by the afternoon.<br> <br> It is now 3 November, almost 2 weeks after the original request and my contract is still active. I want to move to prepaid - why is it so hard! Why can't someone do this! I have reference numbers! I want this contract moved to prepaid NOW!<br> <br> Regards<br> Darshik
