UNUM is trying to intimidate and strong arm me

It appears that UNUM is trying to intimidate me or strong ARM me. They closed my case because I didn’t give them the information they requested. My reason being I felt they were dirty because after having my stroke. I let a representative come to the house to check me out. I gave him the stroke information. A copy of my award letter from SSDI resulting them reducing my income from 1500 to 151 aproximately. I signed a paper for them to keep the 151 dollars. They want me to pay them back for $4994.01 by 4/18/11. Giving me two options to pay. Neither of them making it easy knowing I receive $1476 a month. No medical insurance until 2012 so I have to pay out of the pocket for medicines and doctors visits. I haven’t contacted them because I know it’s going to make my blood pressure go up and I don’t want to die like that. If I knew at the beginning that I had to pay back any money. I signed a paper in 9/09. It didn’t click because I felt despair to receive income to pay some bills. Later after speaking with other people then realizing that if they give me money for two years and I have to pay that back. It would be probably be $20,000 or more. That’s why that lady didn’t want me to apply for SSDI. I did it anyway. I don’t understand the game they play in the insurance industry. I take the blame for my ignorance for signing with them. I need help fighting the big bad wolf. I’m waiting for them to sue me.
