DATA *******!!!!!!!!!!!!!!

Vodacom *****s data and that is a fact!!! I have my mobile data switched off at home because of wifi and I have my wifi assist in my settings off...and as usual...while at home, Vodacom does not inform me that my data is running low. I receive a message at night stating that i have no active data bundles!!!! How is this possible!!!! Vodacom please STOP *****ing my data. I am on a contract so basically there isn't much I can do at this stage but I cannot wait for my contract to end to move away from this horrible networ****
