Vodacom *****ing airtime with unathorised Data refill services

Vodacom debited my own airtime on a daily basis and force 10mb into my account. This service called data refill! I never opted in or subscribed for this service, even after I cancelled this service, my airtime was still debited! I am a Vodacom client for over 15 years, never have I ever seen a company *****ing from their own client! My simple request was to refund all my airtime that was debited for data refill without my consent, now they claim that I have used the 10mb data which I never needed or bought! They will even debit my last R3 and give me 10 mb, making my life very difficult should I had to make calls. I never had any problems with Vodacom, but this is just a heads up for other people that might be a victim of Vodacom data refill service. I called in and the operator cannot even lay an official complaint for me, I need to do it myself... So unhappy and angry now!
