I’m NOT an attorney NOR do I play one on TV but most any “general practice attorney” should be able handle this relatively simple issue & W/O much $$$$$$ or hassle.
My own lawyer, from my little NE Texas town, once fixed a similar problem at GMAC with a phone call & followed it with a letter (for which he charged me 50.oo), that DEMANDED that the company admit their error & “clean-up” my credit report. - He then billed the finance company for his fee & so I ended up owing him ZERO.
After that is done (and NOT before) consult a SLANDER/LIBEL practitioner & follow his/her advice on the need for a civil action at law.

First piece of advice: Don't take legal advice from anonymous people on the internet... ; )
That being said, with an issue of this type, the problem is often less legal, than practical. The consumer is on the phone with a poorly paid customer rep who, even if they completely understand the problem, is only empowered to select one of a limited number of options on the computer screen on front of them.
"Admit we screwed up, reduce that admission to writing, and send it off to credit reporting agencies" is probably not one of the options, so the customer rep is never going to be able to make it right.
A call, or certified letter, from an attorney will often get the problem "kicked upstairs" to someone who is authorized to do something that is not an option on the customer rep's screen.
