He installed the wine glass holder upside down and he didn’t secure the wine rack. There’s a pack of wedges that he should’ve screwed in to secure it in place and he did not, so it can be pulled out  I don’t want that. He left the package on top of the unit before he left. I didn’t realize what it was for until he left. I read the manual to trace his steps because I couldn’t figure out how to hang my wine glasses. That’s when I figured out his mistakes. I’m NOT happy.
