Just when I thought things were getting better....I get told I have to have 524.63(2missed payments) by March 9th so my car can avoid repossession. Then another $250 by the 12th to, again, avoid repossession 😢 that's the only car we have. We need it!! Idk what to do. My fiancé just got a job. So that helps. But idk how we're gonna get the payment for the 12th 😢 prayers please
