I wrote and mailed a certified letter to Experian and XXXX, regarding accounts on my report that are inaccurate. It has been 30 ( plus ) days, since someone signed for the papers, but I have not heard anything. I have duplicates of a debt ( private student loan ) and accounts that were made current, which are negatively affecting my credit. Also, an account that has some missing positive payment history, was not updated on my credit because the bank does n't want to improve my credit score.
