I have a problem cancelling my Hughes net account after an accident left me unable to work.

I have a problem steaming from my Hughesnet service cancellation. This started when I received a bill from Hughes dated 12/09/2015. The bill was for 78.15 and said they would suspend my service if not paid. This was troubling because I had hurt my back earlier that year and could not afford to have Hughes net. I assumed it was closed but they said evidently the account had been put on hold. They ask about this at the time but I assured them I would not be able to afford the payments then either because of my disability. I called Hughes net on 12/21/2015 and spoke with Ms Gonzales case #51671513. I explained everything to her including the fact that I was now unable to work. she was very nice and she said she would credit the $78.15 back to the account since it had not been used for 8 months and should have been closed. She also sent me a box to return the equipment in and instruction on what to do. I sent all equipment back the same week I received it. I thought everything was fine but then on 01/08/20@6 I received another Hughes Bill, this time for $264.87. I again called Hughes and spoke with Me Rodriguez. I explained that I was still unable to work and was waiting for my disability to start. I explained that I did not have 284.00, if I had that kind of money I wouldn't have cancelled my service. She basically didn't care and hung up. Then on 02/22/2016, I received a letter from a collection agency saying they were contacting the credit bureau. I still do not have $284.00 and now the interest rates on my credit card will be increased. This is because I have been forced to us credit for many things during the year and can't afford to pay high interest. I understand about penalty but I do feel something could have been done due to my circumstances. If anyone could help me in this matter I would appreciate it. Right now my good credit is al I have left. Thank you
