Done-Rite Painting

I had my rented home Main Bedroom and Ensuite Bathroom Painted and the Ceiling redone. The fellow who did the work was in and out all day and did not take his shoes off or put down sheets in the bathroom. He would come in for maybe half an hour, paint a bit, then take off for awhile. I found it very strange. The paint in the ensuite has started to bubble and they are coming back to see his work and hopefully redo the walls. Looking forward to getting this resolved.
