Crochet mural Stiner

I ordered the robe hook in chrome. When it came, there were no instructions and the hardware looked wrong. My husband and I were not able to mount the hook on the bathroom wall. Our handyman concluded the screw that came with the hook was not the right type of screw. Looks like I got something that was returned by another customer and then repackaged without the correct hardware. Wayfair has informed me the window for returns has passed so I'm stuck with a useless hook. Not happy.
