Dear Friend,
Sorry to hear this happened to you. There is a answer above my answer given by our friend, but I beg to differ and therefore I am giving my answer below. I hope Smartpants would not mind.
There are two aspects involved here. FIrst let us take a look at your Insurance Company. If you are sure that you were explained that the payouts would be just reduced and nothing more would happen than this, I think your insurance company has resorted to to misrepresentation and wilful concealment of facts to you and yes ... you can fight against it.
For this you can apporach National Arbitration foram as they also cover Insurance related matters and take the arbitration in your favor http://www.adrforum.com/main.aspx?itemID=246&hideBar=False&navID=70&news=3.
This would be a cheaper alternative than filing a lawsuit. You can reach National Arbitration Forum at P.O. Box 50191 Minneapolis, MN XXXXX-XXXXUSA

Regarding your SSD Issue, please note that The first thing that usually happens when an overpayment occurs is that you will receive a "Notice of Overpayment." When the overpayment is work-related, a breakdown of your reported earnings is included in the notice. If you disagree with any of the information Social Security is basing their decision on, you have the right to file an appeal. If you agree with the overpayment amount, then the next step is to begin repayment negotiations.
Coming to your issue, since you do not agree with this, you need to go in for a appeal against this. Please note that Social Security is allowed to use only IRS refunds to offset SSDI overpayment debts. This option is only available if you are: 1.) no longer receiving SSDI benefits, and 2.) refusing to make payments to Social Security.
To file an appeal, you will find detail Appealing process at http://www.ssa.gov/pubs/10041.html
you can call them toll free at 1-800-772-1213. You can locate your nearest field office using your zip code at https://secure.ssa.gov/apps6z/FOLO/fo001.jsp
You are on a sound standing and you have facts in your favor. I am sure, if options listed above are exercised, both your Insurance Company and the SSD people will be taken care of.
I hope the above helps...
