MFC Agent came to my house at 20:00 to reposses ve

My car was reposed earlier by one of the agents who came in and demanded the vehicle. when I told her I already had arrangements to pay on Friday - 4 days time, she told me she couldn't do anything about it. her responsibility is to take the vehicle. I signed the papers as she demanded and handed her the keys. after doing research into the ******** collection, I phoned her back and totally denied everything and told me it was voluntary and all that. what a shame. I am only behind with 30 days.
