turns out it might of been the facebook messenger app. I asked the boss if everything is good, and administration say "your data usage is not over the limit" that tells me they don't know what I'm asking, and also haven't actually answered my question.
fuck it, if they haven't had a bitch to me about it ill leave it.
but yeah, facebook app...
oh, and that so called "tech head at work" still never got back to me...
