Car still on finance and needing a second gear box

[Guest]

Hi. I am reaching out in desperation. I brought used juke with a cvt gearbox in October 2017. By March 2018 it needed a new gearbox over £4000. I complained to my finance company and they arranged the dealer to cover the cost of repair. Now the gearbox has gone again I've had the car less than 3 years. I can't afford the £3000 estimate for repair and the cars not worth much more than that. I have 2 years and 3 months left of the finance and have no idea where to turn. The company that replaced the gearbox in March 2018 are no longer trading. Surely a gearbox should last longer than just over 2 years? Thanks
