"upgrade when I requested cancellation" and now I can't cancel because of the technical back end office!!!!

<p>When I tried to cancel my contract (the network is awful and my phone won't send sms's - apparantly a glitch with my account that no-one can solve) on the 14 Jan 2017 I was upgraded instead. I want to migrate to prepaid and despite endless phone calls and escalations from the call centre, the technical department has not lifted the unauthorised upgrade so the system won't accept the cancellation. </p> <p>I have spent hours with the callcentre and the most I get is a request to phone in 2 days to see if they are able to execute the cancellation. 2 weeks later I am still being told to phone in two days. I have even tried reporting Vodacom to their own ***** line, I have left at least a half dozen very dissatisfied user feedback messages and absolutely nothing happens. </p> <p>It is dishonest, ineffecient, ******* and it seems its due to the' back-end technical office' being unable to deliver. Any idea on how to get to the technical people to do their job??</p> <p>Dont even think about signing a Vodacom contract ! You can't get out of it even when it has expired!</p>
