If you're a business subscriber, you will need to call the business subscriber help line, as this community is only for residential subscribers.
There is a specific procedure for dispute resolution. Please see https://legal.hughesnet.com/BusinessSubAgree_3-16-17.cfm, section 19.
Though I don't know how business support handles sales call reviews, if you feel that you were misled during your sales call you may want to request a review of that call to determine whether this was the case. Please keep in mind, however, that if they can do this it will be with the sales call for your current service, not the original sales call for which you later called and cancelled.
Good luck.
