R300 AIRTIME VANISHES

I had R300 airtime at 05:00 am today, put my simcard in a new phone bought yesterday I had data on my sim if I may add... <br> <br> From 06:15 till 09:10 Vodacom managed to ***** R300 airtime from me... called the call center spoke to some guy who sounded more interested in the conversation going on behind him, he didn't listen to my request I asked to speak to a manager then Tintswalo Maceke came to the phone introducing herself as the supervisor on shift! She was so rude to me her explanation was that I have a 4g SIM card! Her nerve she even asked if my data was on or off when my SIM card was inserted in the phone??? Who checks that?<br> <br> Can someone interested in helping me please do so
