If you subscribed directly via HughesNet (and not via a reseller like Dish) I suggest you request a review of your sales call. The company keeps a recording of the sales calls (but only for a short time, about 3 months) and the HughesNet reps on this site can pull the call and review what was said. If the sales person misled you or neglected to tell you information they are required to give you, you may have recourse.
To request a sales call review, all you need to do is reply to this post and ask for the review. The time frame for the review can be up to 7 business days, and you will be given the results of the review via private message in this community.
