If that is the case why don't you post your transaction ID if you really think that they scammed you, you should have waited a day or two to start a scam accusation like this for a reputed site like this which is running smoothly for a long time, you could have started this in scam accusation instead of bitcoin discussion if you really think that they scammed you and i would like to know the transaction details or the amount to validate your claims, if its more than ten plus bitcoin then we can understand if not it is too early for an accusation.
