[quote name='wilsonr']The chance of receiving a negative is exponentially greater when a payment disputed is escalated via Paypal, your only recourse when receiving a negative feedback in a situation like this is to respond in kind (in a professional, factual manner.) Then, say after three or four days, initiate the mutual feedback withdrawal process. eBay is actually encouraging sellers into this action, although in an oblique manner, when negative or neutral feedback is given for a transaction.
Also, while everyone is correct in this thread about shipping only to a confirmed address, the buyer could easily win the dispute if he states the item is significantly not as described - which may seem ridiculous as that situation isn't applicable here but that doesn't really matter.
I would recommend two courses of action: first, attempt to ascertain, in a very round about way mind you, how knowledgeable the buyer is about his charge back rights; second, attempt to contact the receiver of the package, perhaps even the post office responsible for delivery, to see if you can nip the situation in the bud and either redirect the package or have it returned to you.[/quote]
In order to win a dispute on that grounds he would be required to send the item back first.
Contacting the post office won't do squat. They can't due anything once a package is en route, you can't prove your the person who sent it and they won't do anything to interfere with the delivery of the mail.
