Update:
The seller got back to me over the weekend. We exchanged a few communications, and he requested photos of the item that arrived. I sent them. He agreed to refund my money and sent me a prepaid label to return the item (to Amazon.)
He promises to refund me in full once it arrives. He cautioned that it may take 7 days and to please contact him first before leaving negative feedback.
I dropped the box off in my company's mail room this morning for UPS to pick up later today.
