Actually, no where in the contract does it state that you can move service any time you want, it does state that you are bound to arbitration though.
The only system where one could freely move around on is the HN7000 system, which required the user to have some knowledge of installing and pointing a dish if they wanted to relocate frequently. The HN9000, HT1000, and HT1100 are not easily moved because they are dependent upon beam, and all service plans for those units, depend heavily upon geographical location in amount of data available, as well as costs.
But, Hughesnet does offer a service where someone can freely move service, once, during the contracted time.
If you feel you was misled by a sales rep, then Amanda, Chris, or Liz can pull your sales call if it was done via official sales channel to verify your story. If you was misled about service, you may be able to terminate with out an ETF.
