CAN'T WAIT TO DUMP VODACOM!!!!

I contacted Vodacom on numerous occasions lately to find out why my phone was chewing up data (60mb in 2 days - when all I had done was send/receive 8 Whatsapps (with no pics) during that period. Eventually it was recommended that I turn off a certain app. I went a step further and uninstalled the app, along with anything else I could uninstall or turn off. All this has been unsuccessful - now I have turned off the data completely and only check now and again for messages. If I don't do this, my data is chewed up, my call limit is exceeded, (by far more than the R50 I have allowed) and on top of that my phone is blocked until the following month - when the whole cycle starts again!!! I CANNOT WAIT TO DUMP VODACOM IN AUGUST!!!
