Broken agreements.
Even though we pleaded with them to be delicate and move slowly, the movers still smashed a lot of stuff. A mover in front of us shattered a dresser drawer when a drawer slipped from his grasp while he was skipping (yep, skipping). A chest that is one of our treasured possessions was then scraped up. Because the staff neglected to bring the necessary hardware to the residence, a bookshelf could not be put back together. I believe Johnson, the team leader, promised to return the following day, so I waited all day for a call informing me that he had returned with the hardware and had put the bookshelf back together. He returned the day after I phoned corporate, but only after finishing up at another site and arriving hours later than expected.
