Contract cover

If I had my way I would've canceled my Vodacom contract long time ago, it's one battle after another with them. I have been trying to cancel contract cover that was added to my contract without my permission it has been 8 months now they have been deducting this amount. I always call customer care every month to cancel but to my surprise they deduct. Last month I was fighting them they made me pay reconnection fee after they suspended my line knowing very well that I had confirmed ***** case connected to that line. I'm so frustrated with Vodacom.
