User Moparofficial not responding..

You’re missing the part where the seller read that the part was not correct for the buyers application, but he already gave the part to his buddy at FedEx to ship. Then he called his buddy to stop the shipping So it wouldn’t be delivered, probably because he felt as if he would refund the money. Then he saw that the guy posted negative feedback and started this thread, and maybe his mind changed about refunding, but doesn’t have the part because the shipment was halted. Now he needs to wait until he gets the part back from FedEx, or he too will be out the money if he refunds, and not have the part until it gets returned by FedEx, further complicating the transaction. A transaction, by the way, that he thought was complete, but now must deal with again during his already busy life.

There, did that fill in the blanks?

The "buddy" at FedEx is his wife. Little chance he was going to have a problem getting it back. And if he pushed pause he knew the transaction wasn't complete or he wouldn't have pushed pause. Add that he had enough time to do all of that but not respond to the buyer?

Should it have gone public (late Monday, BTW)? Maybe not. Regardless of private or public, the seller had time to see the message and infer from just the header that the deal was going south and should have responded before the buyer had time to go public.

Communication, communication, communication. The seller didn't have any and so we find ourselves here.
