<prompt> Human: About 3 months ago I was in Shanghai for work. After a night of drinking I followed some local people I had met that night into a cab, and we went to a sketchy place. My 2 friends left the room and suddenly I was choked by a couple of guys and threatened. They said I had to pay Y60,000 about 10,000 USD or I couldnt leave the room. So I signed the bill and now my bank wont reverse the charges despite repeated conversations with them about the situation.After being choked I was scared shitless, and the guy who put his hands on my neck said his friend was with the police so I didnt file a police report. I applied for fraud reconsideration but the bank reviewed it and denied my claim after a lengthy process. They say I can send in a new reconsideration, but only if I produce new evidence. I have no paper trail, so what the hell do I do? Its my word against my signature, I feel like Im fucked  <response>: You were set up from beginning to end. Im sorry this happened to you.Even if this happened at a club in the US, youd likely lose a lawsuit. I imagine its even harder dealing with Chinese laws.
