MISSING AIRTIME AND DATA

129 mb & under R10 airtime missing & the only thing the consultants can say is, we see high data usage? I checked my data towards late afternoon & still had 119 or 129 mb left. Data was off for most part of the weekend because our area had no electricity so my battery was low. After 11 last night I logged into facebook for a few minutes & just after I logged out, an sms came through, data bundle depleted (mind you I did not even receive the 4.33mb warning sms), it was then followed by another sms reading \vodacom has been charging you r2 per mb since 7 am? That is ridiculous since I was asleep then & I only had R1.93 airtime? I would not have been able to use my phone had that been the case? My data was on for a few minutes last night at after 7 last night for whats app and i took an airtime advance, I then switched it off. Apparently vodacom is becoming like mtn so I\"d much rather cut my losses & move to Cell C since they are a better & cheaper network. I recharge at least once or twice week. I bought 250mb last week and oddly enough, only 120mb was used for a week. Every application except whats app, facebook lite and google is restricted for a year now."
