GMAC has placed a bad mark on my daughter's credit. After losing her job in 2004, the last 6 mos. of her car payments were made but some were late. They also stated they charged off the last payment, which is untrue, as she did pay it late and has the title to her car. She is now trying to purchase another vehicle, but the bad mark from GMAC is giving her alot of problems. She hasn't been able to get help from anyone she calls ar GMAC. How can she get that bad credit mark erased? Thanks for your time, Ann
