If it's been no more than 90 days since your sales call, and your sales call was through HughesNet itself (not a 3rd party reseller/dealer), you can request a review of that call to verify what you were told. If it's determined that you were, in fact, misled about the service, you may have recourse in the form of being able to cancel without the ETF. You can request a sales call review in the "MyAccount and Billing" section. Make sure to specifiy what it is that you believe you were misled about.
