Massage Envy review: charged my credit card and told me they hadn't!!

Went to Mission Valley-San Diego to buy a gift certicater this morning. I was never treated so badly in an establishment. I had to wait over 10 minutes to complete a transaction. First they would not take a $100 bill and I did not have smaller bills, then they took at least 5 minutes to get my credit card approved and I signed no receipt. When I asked for a receipt all of a sudden a woman who says she was the manager demanded my credit card again saying the sale did not go thru even though the sales gal told me it had been approved. They refused to give me a paper receipt and at that point I told them that I was not going to wait another 10 minutes for them to learn how to successfuly conduct business and the manager demanded I leave because she didn't like the tone of my voice and said she was going to call security. I left without the gift certificate. I called my credit card company immediately and found out that indeed the transaction did go thru contrary to what I was told by the manager. I want an immediate reversal of those charges $100 that were made to my Visa Your full cooperation would be most appreciated.
