No one is defneding them, I believe he is blaming you for not checking it out before hand, it took me about 5 secs to click the terms of service on thier website:
Fair Access Policy
To ensure equal Internet access for all DIRECWAY® subscribers, Hughes Network Systems maintains a running average fair access policy. Fair access establishes an equitable balance in Internet access across Satellite broadband services by service plan for all DIRECWAY customers regardless of their frequency of use or volume of traffic. To ensure this equity, customers may experience some temporary throughput limitations. DIRECWAY Internet access is not guaranteed. This policy applies to all service plans including "Unlimited" plans where customers' use of the Service is not limited to a specific number of hours per month.

I have thought of using them many times but would never agree to something where they can turn you off at thier discretion, with no hard limits, and still expect you to get paid for it.
AND sales people lie all the time, as long as the truth is in the contract you signed afterwords your fault for not reading it all. Or do you really believe that every single site on the net "has the hottest women on the internet!!!" If people signup and dont read the TOS then they are at fault, people dont take personal responsibility for thier decisions serious enough.
