I mailed off a wiring harness about four months ago to an individual I had heard about through social media. I have no idea whether he's an actual registered business owner or not. The item spoken of was an engine wiring harness. We agreed initially that he'd be finished with said harness in a couple weeks. Clearly that wasn't the case. I've reached out multiple times asking him to send my property back. He went a month at one time ignoring all communication. I finally spoke to him again Friday where he apologized and assured me he'd have it in the mail this previous Monday. Yet again that's not the case. I'm sick of being run around by this guy. I've figured out how to do what's needed on my own and need some help getting this guy to send my property back. I have all conversations in jpeg screenshot form if proof is needed. Thanks
