Best plan?

My father has hughesnet service. 20gb plan. He lives in a very rural area and aside from dial up this is the only available internet provider. He has The Dish for TV service and previously had their internet service. Was told he needed an upgrade (hooper device) when in fact it was just a sales tactic. They came out to upgrade him, took away his DishNET internet and he some how got signed up with Hughesnet for a 2 year contract. He can't use his TV for any streaming services, can't connect his cell phone to his wi-fi provided from hughesnet. Can't get out of contract unless he coughs up the early termination fee of $400. He is 81 and isn't a gamer, doesn't spend hours a day on social media and buys minutes and data for his cell phone. Where is his hughesnet data going??  He isn't interested in buying tokens. Considered increasing his data to the 30gb plan but is that really going to be enough? They won't let him buy the equipment since they state he was started on a lease plan and it is not changable. He never had any idea what was going on and the powers that be say it is his fault for not listening when he had the contract explained to him. Seriously?? Did you ask if he had his hearing aids in? Did you understand him with his paralyzed vocal chord? He is a very trusting soul and believes people are good and don't typically take advantage of others. Sorry but he was taken advantage of and the behavior displayed by the company over the past week has been shameful. Elderly abuse? I don't live near him but have tried to help him by phone and chats with hughesnet. They really don't care about their customers. Sorry for the lengthy vent post. Just trying to figure out a way to help him since the company won't. Should he add more data to his plan to be able to actually use his internet for something other than checking his email?
