You have explained here one of the ways in which you can have a contact set aside: fraud.  Another is misrepresentation.  This case fits in to either scenario.  If there was fraud in the inducement to contract the contract is void and you should be able to get all of your money back here.  I would seek legal counsel in your area on this matter.  Bring all the paperwork that you have on the matter.  Also, if you remember the names of the party ir parties at the agency that told you that she had never been through the process tell it to the attorney.  You should be able to walk away from this.  Good luck.
