Vodacom *****ing

I have two vodacom prepaid sims and recently that my airtime is dissapearing at a fast rate. One is due to an ******* funeral policy and the other due to an ******* supscription. I cannot understand how they can do this without my permission. They must be coining millions in this way. And on top of it all, impossible to contact them regarding this. But within a minute or two you can get a policy. I have been trying for three weeks now to cancel this. I feel sorry for millions of other people. All I can do now is to take legal action.
