What can we do?

Hello, we are EC in Florida. We are working on a project, originally we were hired by the someone working with the GC. Then the owner fired the GC and took over under their own license. We never submitted a NOC to the old GC or the new GC. With corona we stopped working there for a month, now that we have to get back to the job we still have not been paid. They want us to go back to finish the job but we are wondering legally what are our options?
