Who I have the same questioned this topic

I purchased a Jetpack Oct 17, 2013 - yesterday !  I was told we had 5MG to use, that we would never use it all in a month.  WELL by 11:00pm I received an email that we had used 90% already.  What the heck is going on ?????  My son watched a movie and did normal stuff on his phone that he has always through our wireless internet - Wifi with Armstrong.  We had to add this for a different location where Armstrong does not have service.  Not at all happy with Verizon right now.  Ready to cancel phones and call !
