The Equifax credit bureau continually reports old, outdated information on my credit file, particularly 1 account which was paid off over 1 year ago in XXXX 2014 is still being reported as an active collection account even though the collection agency indicated in writing that they have been reporting a paid in full status and XXXX balance. 
Also, I have tried disputing old, outdated information online, however, Equifax stops the online reporting process indicating they can not verify my identity and who I am. 
Which entity or agency XXXX credit bureaus which make their living by publishing old, outdated information, so credit grantors can make more money and profit because bad information is being reported on consumers?
