Just don't: Lack of professionalism, supervision and pride in work

I was charged a lot of money for sub standard service. There was no supervision until the moment they finished and I asked that someone walk through and check the work. Crack started showing a few months later. I have paint chipping in places less than a year later. The one painter sort of cleaned the tiles outside my kitchen door after we had to ask that they clean up their mess. After having sort of cleaned it there were still marks and my wife was told it will come off with soup. Meaning she must clean it. They arrived early in the mornings while we were still having breakfast, without proper equipment and would just sit there waiting. They left before 3pm each day and tried leaving at 11am on the last day. There are many 'hidden' spots that weren't painted. The owner apologised after I complained and came to the house with a worker to fix some of the shoddy workmanship. It was a little rainy so they left and never returned to finish up.
