Data and airtime missing, everytime i recharge.

Last week, I've been trying to get hold of vodacom regarding my missing data on my contract router, even today i have not been assisted or advised what is it that depleting my data. i went to vodacom store at Boulders shopping centre , i was not assisted. Yesterday i went to Carlton centre vodacom store and again i was not assisted. They keep telling me about the 3D system they migrated to, which i don't understand whats that has to do with me because as a client i just need help and solution. So since yesterday I've been trying to buy data using my prepaid vodacom number ***, again my data and airtime are been depleted without even using them. <br> <br> Your client service is very disappointing.
