What happened if you were behind on payments and the lender offered to refinance and lower the payments and said you were approved and then repossessed the car?

Generally you would have to sign paper work if the bank had approved a refinance agreement . In that case you could take legal action . They could however reposses the vehical if you fell behind again on your payments after sighing the agreement. Guess what......... banks and lenders LIE !!!!! If it is not in writing then there is no agreement so you don't have any recourse. Unfortunately you learned the hard way.
