Citi Financial ripoff Ohio Florida

I purchased a vechicle through Citi Financial Auto.The vechicle lasted 3 years before the engine and the transmission gave out.The purchase price for the car was over 7,000. And I still owe 5,600 maybe a little bit more on it.They called me for a payment and I told them I couldn't afford to make any more payments on the car, and then pay for repairs too.And I told them to come and pick the car up,and they refuse to come and get it,and they are still calling my house asking for payments.I tell them every time they call that I can't make the payments due to me putting money out to get the car fixed.They told me if I was to put the car into the shop, that they would pay very little towards the car, and that I would have to pay the rest.I went to the machanic to get a estimate on the car, he said that the car would cost around 1,500 to 2,000 to be fixed.Even if I get another car I would have to pay for the car that I got from Citi Financial Auto and it's not any good.If I was to get another car, I would have to make payments on it also. and that would be very dificult on a fixed income, for disability from social sercurity once a month.What do u think I should do?
