Said the part didn't arrive. I could see by the tracking it was running late so I sent another. He said that didn't arrive. I checked tracking again and he had the part 3 days after I posted the first one.
Then I had messages saying it hadn't arrived, so the guy is a fraudster and I reported him through ebay and added to the blocked buyer list. Looked up his name on Facebook and blocked him on there too, to make sure he can't see the products I develop.
