Spas Inc. Never paid Overtime. Illegal Business practices Marathon Florida

I worked at Spas Inc as a bookkeeper for 4 weeks. I was in charge of accounting and payroll. No employess is paid legal overtime. All company vehicles had expired tags. The owner "Mike" has an expired drivers license. He is not wven a licensed contractor. He uses old owners license to do work. He pockets cash from register. His books are false. After bringing these issues to his attention, he tolde i was dumb. I quit. He still owes me amd other employees overtime. He also is telling everyone i was fired because of stealing.
