I had the same issue with my movers who were big name movers. When I saw my Viking D1 in it's original box at the bottom of a tall pile of boxes of hardback books I screamed. They came back and said they knew how to pack. Luckily I kept all the packing material in my machine box so that must have protected it somewhat as I had no problems with my machine when I used her for the 1st time. I continue to keep all my machine boxes and their packing material for that main reason as I have sold a machine or two since my last move and having their boxes made it easier and safer.
Sorry you didn't fair as well.
