I am really new to this and please excuse my ignorance. A few days ago I accidently stumbled upon some letters of good faith. I am trying to get the only negative mark I have on my credit report removed. I cosigned for a loan for my son and he was 30 days late one month, when I was out of town. My credit is excellent and I am offering to make up any late payments on this account and pay a month in advance. I would like to find those letters again. Please HELP.
