I was trying to purchase 10 movie tickets so I put in my Stubs number & credit card info when I discovered it would only let me buy 9 so I changed that number. I didn't realize that it kicked out my Stubs info so it charged me $11 service fee which is waived if you have a Stubs card. I immediately tried to contact them by phone and email but No response. One week later and still no response. Guess I'm out $11 bucks. I have also contacted AMC.
