Neved. There are a few things that you can do to lessen the chances of something like this happening in the future.
Only trade with people who have a fairly high trader rating. What that cutoff is, is your choice but I prefer at least 7 or 8 positive trades.
Make sure they're "vets" but then again sometimes you can get a bit screwed by them as in this case.
Make sure that you have full name, number, email, home address.
Make sure that they're fairly "well known". How, you do that is a bit subjective but if you get the feeling that they're well known then there are likely people who can contact them and can also vouch or act as a middle man.
