I have one 60 day delinquency on credit report. However, I compared three credit bureaus, I realized that the month of my delinquency is not match between experian and TU and there is no 30 day delinquency before it. More interestingly, I had experian report on Aug 2011, shows delinquency on Jun 08 and I reviewed again on Jan 2012, the delinquency moved to July 08. I called TU for disputing inaccuracy. TU told me OC could correct the month delinquency between bureaus and added 30 day delinquency before 60. Could it be possible? After I dispute, can it delete the inaccuracy information?
