If he was seen on Facebook lately, then I guess he did turn out to be a douchebag after all. That's too bad. He seemed to be a regular consistent poster for awhile. What makes people all of a sudden become dishonest?....I don't know. Did he need the money that bad?Plus if he is active on Facebook as others have said then he basically took the money and ran.
In the future I would/will use Paypal or something similar to send payments where you have some kind of fraud protections. I use to have no issues sending personal checks and cash. Not anymore. I am not sure if using credit card checks for paying for stuff is protected like when you use the card? Just having a 3rd party to fall back on can ease some of the stress of worrying about getting ripped off.
And the worse part is the OP not only lost his funds, but he did not get the parts. I know, this is Captain Obvious, but it is a double whammy that is just a crappy situation. The whole situation stinks!
I hope Doug is able to get some satisfaction out of this situation.
