Get it subscription Still not cancelled

When i took out the initial upgrade contract I specifically requested the get it service to be cancelled. I was told by the instore rep this will be cancelled as soon as the new contract comes into affect. <br> <br> Months later still not cancelled, I contacted Cell C again to find out what was going on, then told I had to cancel this in writing. So in Nov 2015 I did this, with the hopes this will finally be cancelled. Even received a cancellation reference and email stating this has been cancelled.<br> <br> Feb 2016, and I am still being debited for this useless service!!! <br> <br> I want a refund for ALL the incorrectly billed get it service for all the months incorrectly billed.<br> <br> Cancellation ***
