F--- Hughesnet

Hopefully, I can get through writing this. When I got my new job back in July, the new income permitted me to move to a place where I could get high speed internet through a cable provider. The old place was too rural and couldn't have cable, leaving dial-up and satellite the only options. Enter Hughesnet, with their limited data connnection of 200MB/day, mediocre customer service, 80USD/month bills for so-called service, and 400USD early termination fees (despite only being an internet provider. Until the day of cancellation, I actually thought the ETF was 200, like a cell provider or most cable services; they offer more than web services, yet the web-only provider charges more. Still, I cancelled, resolving to pay the final 400 over time.
Today, I just get home from work and find a letter from Hughesnet showing a final balance 300USD over the previous one of 400. The extra was a returned equipment fee, because in the move I'd managed to leave the modem in the trunk of my car well past the 45 day return window. I called in to see about waiving the fee if I sent it in this week, only to find out from them that I don't even have all the equipment. It turns out, in addition to the modem and power supply, which I confirmed with them by phone the day I cancelled the service, I have to include something called the Radio Assembly, part of the receiving dish outside in the front yard of a house I moved out of 3 months ago. I have no idea if it's still there. Customer service insisted they not only told me about the Radio Assembly, but also e-mailed me instructions on how to disassemble the dish. I didn't read this e-mail because, as I told them today, I was only told of the modem's return. Why would I need/read directions in identifying a modem and its power supply? Their notes on that call I made back on the 14th are vague, saying only that the "equipment" must be returned, with no details beyond that. So, nearly 1000 is owed to an internet provider because of a 100USD modem (that can be returned right away) and a 200USD dish component that may or mat not be there after all this time.
I'm literally having trouble breathing, and I feel like I'm about to pass out as I can't seem to take a deep enough breath. I'm taking breaks as I write this to catch my breath to quell the dizzy sensation, and I don't even have asthma.
I found out just after the call to Hughesnet that I became an uncle for the third time this morning, and now I can barely stand up because of a stress attack over some stupid bill.

EDIT: It's been about four hours, and I'm a little better (and adding tags). I drove by my old house on my way to get food, and luckily the dish is still there, so I'll come by tomorrow, meet the new owner, and get to work disassembling the dish. I wonder, though, if someone moves into a house and gets the same satellite service, would Hughesnet get them a new Radio Assembly? If so, what happens to the old one, given that while it doesn't technically get sent back by the previous owner, it does get handled by a professional installer with connections to the company?
