Any Lawyers out there? What can I do about this collector's lawsuit?

My wife was served a court summons for an outstanding debt from a collection agency. No correspondence was sent by the agency before this summons, although she did recognize the original creditor on the paper work. She immediately made a settlement arrangement over the phone, and sent them the first payment electronically that same day. It’s been almost two weeks, and the agency has not filed this settlement with the court yet. We have asked them to do this but they still haven’t. We only have a week left before the court date. What can we do?
