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.
