Virgin Mobile Broadband2Go Misleading EULA for Unlimited Internet Access Internet

I purchased a Virgin Mobile Broadband2Go USB modem and Unlimited Service Package.  After 2 days I realized my connection speed had been throttled down to less than 600 kb/s.  I proceeded to contact Virgin Mobile Broadband2Go technical support (or lack thereof).  Where the technician told me that I had reached my limit of 2.5GB of downloads so my connection had been throttled to 256 kb/s.  When I asked where this information was stated in my EULA, the representative told me that she wasn't able to find it.  So I asked to speak to a supervisor, and the supervisor stated the same information the technician did (as a side note, if I wanted to hear a parrot speak I'd go visit my parents and listen to their bird).  So I asked the "supervisor" exactly where in the EULA does it state that Virgin has the right to throttle down my connection speed and she stated that it was on the first page where you chose the plan you wanted to use.  So once again I asked her where this information was stated in the EULA and she couldn't give me that information, mainly because it doesn't exist.  So I asked her to escalate the issue up her chain of command and she refused.  I stated that she could either escalate the issue up or I could file complaints with the South Dakota State's Attorney General and the Federal Communications Commission and the US Attorney General's Office.  The supervisor maintained her stance she would not escalate the issue so I will be filing complaints in the morning and let the pieces fall where they may.
