We hired a couple to paint a room in our house, finish painting the stairwell, &amp; touch up the ceiling. We supplied the paint for the stairwell. They quoted 750 &amp; we paid half up front. 
What we were unaware of, is that they could only paint late evening like past 7/8 p.m. If we would have known this, we wouldn't have gone with them. 
They finished the room &amp; the stairwell. We were having issues matching the ceiling color. 
What should have taken a few days has turned into a two week ordeal. If I offered them half of the money we still owe and "fire" them, WIBTA?
