Still no decent arrangements

Very dissappointing situation. I ap**** for vehicle financing via a company which got finance for me by MFC. This was 4 months ago. We collected the car 11:00am and 14:00 the car was back at dealership as went into limp mode. I contacted the lady who got me the financing and informed MFC. As after a while it looked likes we will have to cancel deal as they couldnt fix car. I got the car back 4 weeks ago. MFC doesn't want to make decent payment arrangements and wants to take car back. My credit is good and the always pay my debt perfectly. This was out of my control. I told them I don't have the car and the lady said she will deal with this and talked about restructure. I understand I got finance for the car bit i didn't have the car. I feel they can make decent arrangements from now on as i now do have the car. But they want to repossess even when they where aware of situation.
