OK; here's the latest and it's pretty good news on my part.
I managed to get to contact the 'other' buyer (there were supposedly 4 N95's for sale.) Luckily, the other buyer had something to sell, so given eBay's rules, you can only contact another member regarding a sale. Anyway, I contacted them and asked if they had heard anything from the seller/thief. He ordered earlier than I did and he hadn't heard a thing either.
So, I contacted PayPal to start proceedings there. No doubt I won't hear anything back from the seller/thief, but it at least alerts PayPal.
I also contacted my bank this morning after seeing that the funds (as yet) had not moved from my bank. They said that they would note my request that nothing to/from PayPal should be 'paid' from my account. So in theory, hopefully, I've not lot a bean. Which is damn good news for me.
I really don't know how these people sleep at night.
Back to the quest for finding a proper N95 now then!
