my car has been repossesed but has not yet been sold and I am 2 moths past due. I ask the bank if they could refinance but the answer was negative what do I do now?

You can try to get a cash advance or payday auto loan. Maybe if you catch up on those payments, they will give you the car back and you can try to sell it. Here is more information on Payday and cash advance auto loans
