Bad trades like this and so many others I see on here and on other places tells me that it is becoming harder and harder to trade btc for fiat and vice versa, I think this is a real problem, someone told me the other day that even cash deposits through bank accounts and wire transfers can also be charged back if someone really wanted, though they are not as easy as paypal.

Can't you get some sort of document from your bank (if you don't already have one) which does not reveal your sensitive information but just enough to prove that it was you who sent the money and it was your bank account?
yes- that's what I have set up today. Unfortunately it takes 3 days and then I have to find someone who can download it to a document file and forward it!. But my time limit on the escrow runs out in 12 hrs and there is nothing more I can do now. I shall have to rely on the bank to recover the funds from the sellers a/c.
