They make it impossible to cancel your contract

I am tired of being overcharged for bad service and have decided to cancel my Vodacom contract. <br> <br> After years of being overcharged and ****med by the company, I am trying to cancel my contract. They make it impossible! I have called their cancellation department (***) several times. They never answer! <br> <br> When calling the normal 111 customer care number, the consultants refuse to, or are not empowered to do cancellations and refer you to the cancellations number. Which again puts you back in to the loop. <br>
