Poor customer service

They're not penalising you.  If you read the service agreement, you will see that they don't guarantee speeds, and that there is a fine for ending service sooner.  The agreement also includes a section explaining the procedure for grievances, which may be helpful to you.   By signing up for Hughesnet, you agreed to the terms of the agreement. 

A lot of people don't have any other choice for internet, so it's unfair to suggest they don't "join" HN.   It's also important to be realistic about the technology -- it is not comparable to terrestrial internet, such as the company you mentioned.  It's a different technology and because of its being satellite internet, it is slower and has less data. 

If you are done with HN, you should stop posting here. This isn't a review site; it's a site for people seeking solutions.   There are lots of sites on the internet where you can post a review of the company and share your experience, and you can warn people as much as you like.  This site is not for that -- this site is for account and tech support.
