Sun Life should have to pay dearly for their screw up

My husband has long term disability with Sun Life, thru the schools system he worked for. Sun Life is not saying that he is no longer disabled. They are saying that they did not know he was drawing a pension and there for have been over paying him. Which was a lie. They knew from the very beginning, when he was awarded his social security disability. Since I had posted last, Sun Life sent us a bill for over $34,000. I sent a letter to them to appeal it. After that they told us that they had made the mistake and over looked the pension. And so they were going to waive the $34,000 +, and just cut him down to the minimum $100 month payment. Which I think is still very unfair, after all, we turned down their crummy low ball settlement (I believe was around $32,000), or draw about $600 a month until he was 65. We chose to draw the monthly payment. After we knew what our monthly income totals were, we bought a home of which, our payments are based on our income. My husband had medical insurance through Social Security. I had none, I tried to get help with getting some thru Indiana’s Hippa. I was denied, our income was a little too much. So, I haven’t had medical coverage since. Where if they had their crap together, we wouldn’t of bought a house that we no longer can comfortably afford and I would of had medical insurance. And then there’s all the sleepless nights, the ulcers over their $34,000 bill! Sun Life should have to pay dearly for their screw up!
