<prompt> Human: I signed contract for them to buy my car for 11,819.00 yesterday. Today they called me and said they cant buy it for that that they can buy it for 9,819.00 a 2 grand difference. Because they made a mistake on one of the features that my car didnt have. Can they do This? I already turned in the plates and cancelled my insurance on it. When I signed contract they said it could take up to 30 days to receive my check and Im just a little hot right now. What do I do?  <response>: If you signed it and they signed it, request a copy of the contract and lawyer up
