Humiliating and rude communication, money back talks ALL the time, treating freelancers like slaves, first he is very happy with your work and promotes you to team lead, then starts charging money back for every single bug in the code (even if there's 1). Very disappointing business manner. Worked days and nights to meet his tight deadlines and made sure his business runs smoothly, promised to pay for overtime work which was not tracked, NEVER ever got paid eventually.
