Thanks for the PM
This article will help you understand the money they took out of her account and why they can do that:

You will have to run your own credit report and see if it appears, I don't speculate on how credit reports work because there are so many errors on so many of them. Monty (the webmaster) has a really comprehensive credit repair eBook and I would suggest looking there since he put so much research into it. You can get it here:

And yes you can settle the debt for less then you owe on your own. Search the forum, there are tons of resources/threads there that answer that too.
RE: your PM, you are asking a “legal question” about forcing them to take the settlement they offered. I am not a paralegal/lawyer so I am not qualified to give legal advice.
I do know however that in every contract there has to be an “offer” and “acceptance” of that offer for it to bind both sides … it sounds like you have a legit offer so all you have to do is accept it now and meet the terms of the offer as outlined. My advice would be speak to a qualified paralegal or lawyer if you are unsure how to execute that or if it will be binding.
