I don't know why it is so hard for this guy to get it right. I am a general contractor not an electrician and I just wired my new garage. I have a 50a rv circuit, a 30a rv circuit, a 240v welder circuit, and a 240v air compressor circuit. I got them all correct the first time. Maybe he or his workers don't want or care to double check their work.
As far as the funny things happening with the hot and neutral reversed, I am not sure. This is now a friend of a friend conversation. I imagine the GFCI circuits acted up.
