Though I truly hope I'm incorrect with this, I seriously doubt you're going to find any satisfaction/answers/closure in this matter.
In another post I'd questioned the accuracy of data usage my account was levied during a period of time when for most of that very same day my area was experiencing severe service interruptions. According to "the meter", we managed to gobble up 32GB on that particular day of paralyzed internet---the same 32GB we reportedly used the day before, when there WAS NO service interruption!
Again, I hope I'm way off but my gut belief is that the people we report and complain to here about our dissatisfaction are either handcuffed in their ability to respond in a meaningful way due to corporate policy and procedures, or are in over their heads because of a severe lack of technical qualifications.
