Excellent customer support.
I had a great customer support experience after buying an office chair. While assembling it, I realized I was missing two screws, so I contacted support through their chatbot on a weeknight before the weekend. The bot quickly routed me to a live person. I shared my order number and the missing parts, then stepped away from the chat. What impressed me was that the support rep noticed I was no longer active, still used the information I had provided, emailed me directly, and offered solutions. That is excellent customer support.
