Orthodontist Closed Unexpectedly And Is Filing For Bankruptcy In The Middle Of My Orthodontic Treatment.

I’ve been doing comprehensive Invisalign treatment for over 2 years and paid off $7k for the treatment a year ago. I just found out today my orthodontist is closing his doors and filing for bankruptcy. He just fired all of his staff yesterday. Fortunately I have all of my trays but I have no one to monitor my progress or change my treatment plan if need be, let alone give me retainers or take my attachments off. I’m supposed to be done in July as long as this third set of refinements actually does the job. My financial status is completely different than it was when I started over 2 years ago so there is no way I can pay for a new orthodontist. I have no way to contact the office to even get my records. Is there any way I can actually get my money back since I paid for treatment that they never completely finished? According to the contract payment was supposed to cover all checkups, x rays, refinements, and retainers when completed.
