HughesNet Non Refund for Equipment Internet

 I signed up for HughesNet internet service on 30 December 2011.  I purchased the equipment for $299.98 with a voice guarantee that the equipment would be bought back for $200 at the end of the 24 month service agreement.

I call in March 2013 to inquire about Gen4 for faster internet download and upload.  I asked if the refund would be available before the 24 month time frame.  They stated that the refund was only for the first 30 day.  Not true.  To be fair they did give me a $200 rebate when I first purchased the equipment.  I told the salesman that the math does not add up and he clearly stated that is right you get back $100 more.  They entered the agreement and now not honoring it.

With new equipment for Gen 4 I am stuck with the old useless modem.
