This is unfortunate to hear TS. I bumped into him several times in Funan on weekdays afternoons so maybe you like to stake out there and confront him when you see him.
I heard other people who are in the same predicament as you. Maybe you all can contact each other and arrange to go make a police report together. One person making a report may have no effect but if more people come out and report against him together, I think the Police may have a valid reason to call him up for investigation.
I bet Sam is monitoring this thread closely. I highly suggest all people who are in the same situation as TS contact TS via PMs and arrange for the next course of action together in order to get your money back. The rest of us can spread the word as well. Good luck TS.
If that wimp Sam really reading this thread, then have the guts come out here and say something. If u make a mistake, be a real man and admit it, offer a solution for affected customers.
Keeping silent only make Sam an even more guilty person. Pui!!
Some of the old CS birds know Sam personally. Do something good like asking him to come out and say something.
DON'T wait for ppl to find yr home address and confront u in yr own home. It will get v embarrassing for u.
