Where is my lunch?!

I placed an order on line, gave me credit card details, approved the transaction on my cellphone and the money has gone out of my account, only to have a window pop up informing me that I was "unsuccessful" and the transaction will be reversed??!! Now what? The money is no longer in my account and I'm also apparently not getting my order either!! I have an order number but am not sure how this is going to be useful? I would appreciate getting my lunch asap or my money back.... I should hope that theft is not part of the KFC menu!
