airtime disappearing

I have been a Vodacom customer since 2009 and I am very annoyed with what happened on my secondary number over the weekend. R150 airtime disappeared and upon checking via Tobi it says the R150 is paid for Vlive content services and I know for a fact that I never joined any content services and my secondary number is only used for calls.

And I have gone through SMS notifications to check if any notification for a charge was issued as Vodacom Vlive website states that you will be notified before being charged and there is nothing. I am also escalating this for ICASA's attention. The no. is question
