Vodacom taking airtime

R10 a day! Vodacom has been taking my airtime by signing me up to applications that I did not opt in for! I read a few articles online about how the exact same thing has happened to other people! You get signed up (somehow) and on a daily basis money is taken from your account. I phoned Vodacom to cancel ALL of these features robbing me blind and the lady on the phone said she can see im signed up to something costing me R10 a day, no clue on how it happened or what it was but she had the ability to cancel it. How can a vodacom employee cancel a subscription that does not belong to vodacom? An article on mybroadband states that "Vodacom rolled out its double opt-in system" to prevent WASP's but I did NOT double opt-in to anything!! I am really not impressed with Vodacom at the moment because their hand is in my pocket and of course nothing will happen about it. I'm considering leaving Vodacom and moving to another network if I do not receive a satisfactory answer and if the problem is not resolved.
