Replying to CALLOUT - mikemonture/trait

So this guy agreed to trade my sunglasses for my boots. He only had them listed for $50 which is sketchy to begin with. So i sent the sunglasses... 2 weeks later i still hadn't received my boots so i sent him a message. He didn't reply for 3 weeks. then finally when i told him i was making a callout thread under the name "mikemonture" he got a new name and he sent me a message saying i was a scammer because the glasses werent there. I called the post office and they still had the package because i put the area code down wrong. so i got really lucky. but non the less he had told me he shipped them the day after we made the deal and he didnt. now he has them reposted under the name "trait" and the story of why he is selling them so cheap is COMPLETELY DIFFERENT. No one do business with this guy you will get screwed over. He has no positive feedback and he's the sketchiest person ive dealed with on ns. Who changes their name and then changes the story of why youre selling them? especially after he screwed me over.

thanks for your time ns i just dont want anyone else to get scammed like i did.
