Did you dispute by writing to the CRA's or did you file an online dispute? It seems that the CRA's use these form letters sometimes as a stall tactic. Or maybe they think if you were not all that serious about disputing the information you just will not bother following up! Did you include all of the info they would need to find your credit report and did you include the acct number etc of the acct you were disputing? Also, were you specific about why you were disputing the info? Possibly, they were unsure how to code the dispute properly??
IN GOD WE TRUST ~ ALL OTHERS MUST DOCUMENT!
