Hi thanks for the reply
In my case I found out that the buyer complained that I had scammed him by taking his money and giving him nothing. Now I will have to prove my innocense to the bank by going to the branch with all the evidence that he did in fact receive bitcoin in return for his payment
Just what I wrote in the most above yours. Forget about punishing your fraudster. Your bank has other things to do, and so does localbitcoins. I guess it's safer to trade with cash in a public place.
