Sprint 4g sprint pcs unlimited 4G was fraudulent. Internet

had unlimited sprint 3g mobile wifi card for couple of years.  was contacted early 2011 by sprint to upgrade to unlimited 4g mobile wifi device and did so.  use the device with a mobile usb router so I can share 4g at home.  had it for several months up until late 2011.  received a letter from sprint threatening me to reduce my usage or they're going to discontinue my service.  I reduced usage and still, couple weeks later, couldn't connect to 4g.  called sprint and they had discontinued my unlimited 4g service.  tried to sell me 5gb/month and I refused.  they essentially had defrauded me by selling me unlimited 4g service which was completely false advertisement.  frustrated and felt I was wronged, discontinued all sprint service immediately.  also filed a report with the fcc and had gotten no response yet.
