Charged my Credit Card & Denied me the Product I was Purchasing

About the time the last call to purchase drinks was made, I went to buy two drinks. I ordered two Heinekens and proceeded to provide the bar tender with my check card. He charged $20.00 and never gave me the drinks. I complained about the excessive charge and he asked for my card back to make corrections(as per 3/20/2008, i checked my account and this transaction has been reversed). HOWEVER, I was charged a another $12.00 when I gave the bar tender my card to cancel the transaction since I had only ordered two drinks for me and my friend but still was not given the drinks. They completely refused to give me the drinks and claimed that the charge was for an earlier purchase yet I did not have any open tub. On further insistence that they cancel the transaction if they can not give me the drinks, I was ordered and escorted by security out of the club!
