I've not gone through the chat log you shared, but I find it hard to believe that your account was suspended without any reason, you probably have done something or break a term of service which flagged your account and it got block, may be bitsler didn't have time or deem it fit to tell you the reason your account is block.

But then again, if you strongly feel that you are being cheated, consider creating a scam and accusation thread on the same board (scam and accusation board) and remember to follow the rules so that your case can be treated properly.
