Vodacom adding services to my RED account I DID NOT subscribe to is blatant THEFT

I like the performance of the Vodacom network, but adding cost to my account without my consent is blatant theft. What is win Sports and Tune you, all Vodacom services I never subscribed to costing me close to R400 a month, totally unacceptable. I never accept and sms marketing or Vodacom marketing call how can they just add this to my account
