Airtime and data theft

Its just frustrating to deal with vodacom, the theft of airtime and data just continues regardless of the fact that this is happening over and over, a person can not even contact their customer services, always busy and you get redirected, where does a person go or request that there should be an audit or investigation into vodacom the company for these complaints, it's time that vodacom users maybe boycott this company, its time perhaps for vodacom to be made public with the ongoing theft problem, I have numerous screenshots of the theft problem what now
