Vodacom Airtime *******

Vodacom stole my airtime on both Monday night and Tuesday morning. When I complained on their Facebook page, I was told I took airtime advance ( which I've NEVER taken in my life). I even showed them proof/screenshot from my Vodacom App which clearly says there's no transaction history, meaning I have never used that service before. The person I was communicating with insisted that the system shows that the airtime advance was taken and used ( by me). I asked for date and amount of the supposed airtime advance and the response I got was "Our feedback remains the same"

Basically Vodacom thinks it's ok to ***** my airtime and claim I owe them, they can't even produce proof that I owe them or how much i owe them. They simply expect me to just let them take it and not say anything. Very disappointing.
