NEED HELP!!!!

What can I do if a finance company in Florida defaulted on a note they purchased from me for a mobile home and land in Texas? They haven't paid in 3 months. I've tried contacting them numerous times without a reply. I am sending them a certified letter demanding payment. What next?

I am a law school graduate. What I offer is mere information, not to be construed as forming an attorney client relationship.

Take them to court seeking judgment in your favor based on unpaid debt or turn it over to a collection agency.
