vanishing money

At 5:30 this morning i had R242 airtime and 350 meg data i drive to work receive a sms at work that i have 3 meg left so i turn of my data.<br> Now i only have R92.20 available and 1 meg of data ? *** happend . Yes i know how to use my data. No it is not background apps all turned of. This is the first time in 11 years that this happened and you call centre staff are trying there best to pin this on me. Even after my data is turned of they are telling me i am using data. Then why the hell does my airtime balance stay the same ?<br> Stop being in component. Audit my account find the problem and correct it. This is bull trying to make me feel like a fool i know more about my phone and data than those call centre guys. How does your airtime get used for browsing if you have data ? Explain that to me
