We purchased $5K worth of lights: 5 Tom Dixon pendants, and 2 Hollis and Morris fixtures-pendant and ceiling. We inspected the fixtures upon arrival but did not check on the canopies and attachments. One of the larger Tom Dixon pendants was shipped without the canopy and ceiling attachments. I talked to no fewer than 4 CS reps whose only recourse (they said) was to contact the manufacturer and hope they'd send me the parts. I asked 3 times to talk to a supervisor and was told they were busy but would contact me. That never happened. Finally, after 3 weeks of nothing, I became a raving banshee and, shocker, my parts shipped the next day. This is unacceptable. The lights are fabulous but I cannot recommend YLighting or Lumens because of this frustrating interaction. Oh, still waiting on those call backs from a supervisor.
