I agree with my colleagues. You have some leverage at this point, and it's important that you don't make a misstep that could result in you losing your case.
I am defending other clients against Wells Fargo foreclosures, and I would be happy to speak with you about your case.
Feel free to call me for a free consultation.

You could file a motion to compel asking the court to order them (again) to provide the documents. Or you could file a motion for sanctions for their failure to obey a court order. In this motion, you could request that the sanctions imposed be that the case be dismissed (although I will warn you that this is always a last resort and rarely imposed).
If they do not provide documents tomorrow at the mediation, you should ask for adjournment of the mediation for that reason, if the documents you're eking are relevant and important to your case, and you cannot settle without them. If there was a written order that the court issued at the trial, then file a motion for sanctions for failure to comply with court order or motion to show cause why they failed to comply.
