Looks like glitch, but support didn't even look on trades? I have wrote to support there were not issues. What's funny, the partner I have traded is known for me, we have contact outside Localbitcoins, however he is offline for weeks.
For me, Localbitcoins (do not know it's their global policy or just some moderators/support/admin) smells and looks they doing something dirty...
Just friendly beware: take off your Bitcoins if you think that's serious case. For me it is, obviously.
