The irony of someone who admitted to scamming possibly being scammed. Anyway you've only left a three hour gap between the PMs, I would give him some time, he might have been held up with something - it happens to all of us. If in a few days he's logged in but hasn't responded then I'd say you have a valid claim.
I would agree except I paid them back with interest although it did take a while...anyway he posted on his thread telling me to piss off with my obvious scam after I brought it up. I think he scammed me, but I am hopeful since the coins have not moved.
