****** airtime and data - DISGUSTING!!

I bought R110 airtime at 6.45am this morning. I converted R29 into 100mb data and within 1/2 hour my airtime and data was 0.00. Even the extra R55 they gave for purchasing the airtime was gone. This is absolutely disgusting!! I then bought a 100mb data bundle and by the afternoon it was gone too!! I went to the Vodacom store in Greenacres, Port Elizabeth and the consultant checked my Wasp and my apps and said she can't see anything open that would use up data. She suggested I phone the customer care number. I then phoned the 111 number and spoke to Nwabisa and she was adamant that my mobile data was on therefore my airtime was used up by the internet. HOW THE HELL!!! I was not even on the internet. I was driving my daughter to school and my phone was in my bag. Does the internet use itself??? I'm very disgusted in Vodacom. This is ****************!!! Can't stand this bad service. Who does Vodacom think we are that they can ***** our hard earned airtime and data like that????
