Our airtimes ****** by unknown content services

Me and my daughter were being subscribed to content services without our consent. First I found out that two unknown services Beefit and Greenworld were added to my account and they were taking my airtime without my knowledge. An agent in one of the Vodacom shops showed me this and helped to remove them, then he blocked my phone for subscriptions to such services. Next day I recharged airtime, thought all resolved. A day later I found out that my airtime gone and same services were back. I called Vodacom call center. Agent informed me that after removing and blocking such services I must wait 72 hours and I shouldn't recharge airtime in 72 hours!!! So I wait 72 hours without airtime just to prevent these services come back. Later on I noticed that an other service VIU Premium is attemting repeatedly to subscribe me without my consent but since such services blocked in my phone it is not added to my account. But today we noticed that VIU premium added to my daughter's account and ***** her airtime. I have removed the service and blocked such services for her phone as well . Now she has to wait 72 hours without airtime. This is unacceptable, and I still can't think of a logical explanation why the hell cuatomer should wait 72 hours to prevent an unknown service to come back? And how come these services added without consent of customer. Please can someone from Voda contact me and explain me this...
