I hope Matias was OK you spelling out his name in full in the forum prior to doing so. I strongly suspect most people don't want their full name listed, especially by someone else.
I also think putting private emails out on to a public forum is also a no no.
The group that left APF have a different way of thinking and I can see why they click over there.
Apart from that, the seller sounds incompetent, and uses well worn excuses, but if he was out to scam, I doubt he would have been in communications for as long as he was. Good to get the heads up on the seller. I think he said he was using a friends PayPal account, all a bit odd.
Sorry to hear you have been strung out for so long.
This weekend I'm leaving 2 eBay negs for a seller
