Guidances in settling arrears

I have lost my job earlier this year and notified the bank. Am in arrears of about 12K as I have missed a few payments. I have recently found a job which pays less than the previous job. The bank is adamant that they want to repossess the car. My plea for reduced installment or giving more time to pay settle arreas are falling on deaf ears. I am willing to pay but they are not willing to advise on the possible processes to move forward on this issue. Their only interest is repossessing the car.
