Wildblue slow downs

When we first got the service from Wildblue it seemed so great! But a few months later it started to slow drastically around certain times of day. Those times are when I need to use the internet of coarse.
  So when I called the tech support they went through a couple steps to discover what my problems were...Get this they made me tell them when I pressed go to load a page while they timed it over the phone on a stopwatch....Then I actually went to a site that tested my upload and download speeds. After coming to the conclusion that I indeed had massive slow downs they sent service people over. Who had checked all the gear and said it was fine.
  So they then told me that the problem was from large usage in my area...This is a convincing conclusion, but can they actually DO  anything about this? i have a year contract with these people and the service not what I expected. Any suggestions?
