I advised PayPal at the time that an Australia Post investigation was underway, and provided them with the case number. In the context of the PP investigation it doesn't matter because the policy GUARANTEES that the buyer will be compensated. At least initially if the seller is willing to roll over and die afterward. The investigation/compensation claim with AP are one and the same thing..

Look, we all have lives that go on in the background. Work, study, whatever. I was not able to devote 100% of my time to the PayPal dispute and subsequent claim. In fact there was only 9 minutes between the dispute being filed and the escalation to a claim. PayPal gives you a maximum of 20 days to actually have a mediated, back-and-forth conversation between buyer and seller to resolve the situation. I didn't get that and subsequently had one single right of reply to put my case across.

Before I had even received the money from the sale of the camera in my bank account Paypal had ruled against me!

In any case, it's very hard to chronologically synchronise concurrent investigations. I have reported to 6 different organisations now and my lack of organisation in the early stages does not make the buyer any less fraudulent.
