DATA gone

Both my phone and data contract have been loosing data mysteriously over the past 24hours. My phones are set up to not run any back-round processes, to not automatically download updates, not to sync with the cloud and most of the apps are set up to run on wifi only, however between 10pm and 12pm last night my phone lost 1gb (i was asleep)

Today i loaded a 1gb one day bundle onto my data contract (which had run out) only to find that it was depleted within 3hours and i did nothing but check my mail, a bit of face book and sent one or two watsapps (text and pics only) there in no way in hell that that constituted 1 gb however that's gone. But no wait there is more, i loaded a bundle onto my phone this morning 3gp 30 days it immediately dropped to to 2.75gp according to the app, only to be restored back to 2.91 gp about an hour later (which is a more accurate calculation of the data spent), please can Mtn explain why my data is going considering i have done nothing on the net to explain the data usage and my phones are setup to use as little data as possible. Secondly how on earth can my data go down and then backup again on the app, seems to indicate that their is problem all round with how your software is calculating usage.
