Fired a drywall contractor

Edit: People keep asking why are the receptacles installed? 99% of the receptacles are on the lower 4'. The lower 4' is OSB. The remaining 1% of electrical devices are shoved inside and not in the way of the drywaller.
Here is this companies facebook review page:

Sloppy work, seams are not staggered, cuts around boxes are poor, rip cutting drywall for unknows reasons, no prefill, mesh tape on ceiling. Constant excuse for not showing up, everyday was a new excuse by the Thursday they had only 16' of the ceiling mudded. Friday they worked from 10am -3pm. Oh ya they had no ladders too.
3pm Friday is when I went and asked why they are rip cutting the drywall, mentioned the window being cut poorly and the 3/4 difference in drywall high when they started the new wall after a corner.
The guy immediately told his crew to pack up before he punches me. lol. I have paid legal and will start the paperwork Monday to get money back from these guys.
