Business ProfileforJFC Pros

On June 29th we had wire transferred 75,000 to JFC pros (amount required by them to start job with a tentative start date sometime in October). After 3 different cancelations on their part for meetings about plans and when we saw an actual plan - it omitted several items we had specifically requested we decided to cancel. I checked with the building inspector to make sure no permits were pulled, and that actual work had not been started or formulated and on July 21st we canceled and requested a refund. They said this has never happened before and not sure how to handle this. After multiple emails and having to get an attorney, the attorneys and both parties agreed to receive a full refund over 4 months due on the 15th of each month starting in September in an equal amount of 18750 in the form of bank check. We received our first payment on September 26th in the form of a business check which then takes 5 business days to clear. When we did not receive our second check on October 15th, my attorney reached out to theirs, only to find out that he has retired and there is nothing more he can do. Joe C did send an email stating that he will drop off the check on Friday the 20th, again no check, and when my attorney reached out there has been no response on their end. They owe me 56, 250 and if we were to go by the agreement which I have included here there would be additional principles and interest on top of that. I have not done any reviews, and did not want to file this, but unfortunately I have no choice. Please help, I am not sure where to turn or how to proceed from here
