the car was parked on the road outsite my home, and I have a witness it was an HP agreement and I did get a default notice, no payments made after that. I sent them a letter asking to reduce my payments, like i did the week before no insurances

Hi All, Welcome reo#d my car today while I was at work, they did leave me a nice letter saying it had been repo'd. I was in arrears, but was struggling with the payment and paying a chunk off my arrears. I sent them a letter asking to reduce my payment, then another a week or so later with no responce. Next, my car went off my front. I think i paid more than a third of the balance, but I'm not sure. How do I get my car back? They say they can sell the car, and make me pay back any losses - if they do that, they can get lost. I need a car for work. No car, no job, no money to give to Welcome. Nick
