AMC stubs program is a complete ripoff

The AMC stubs program is a complete ripoff. We joined the program, and have tried to register the card on the AMC website to take advantage of the benefits. When we try to register it states we already are however when we purchase tickets we still get charged the service fee. We have contacted customer service and they cannot figure out why this is happening and cannot assist us. When I stated we want our money back they state no refunds. They are no help and we continually get charged the service fee for the tickets. Do not join it is a waste of money.
