I disputed a charged-off bill through Experian on March 18th. I also disputed wrong address information and some unauthorized hard inquiries. Experian sent me back a notice that the item was verified and would remain. No mention of the address issue or unauthorized inquiries. I wrote them back asking for proof of the verification process in the form of the name, address & phone # of the person who verified; and to please address the other two issues. I was nice but firm. Just received a notice yesterday that they re-verified the charged-off bill and it would remain. No proof of verification, no mention of address problem, no mention of the inquiries. All they did was re-verify and add a line to my report that said it was verified twice and would remain. Now how ugly and threatening should my next letter be? Should I threaten Attorney General, FTC & BBB, or does that even phase these idiots??
