Online Booking NEVER works

We go to the movies often. I can barely ever purchase tickets online. How can such a massive company have such a pathetic website? It never works the first time. If I'm lucky Ill get the tickets with the 3rd try. <br> I am trying to purchase tickets for Deadpool. I have been trying all morning. I keep getting the below error:<br> <br> ERROR<br> An error occurred during the processing of the transaction, please try again.<br> <br> Why is this happening? Can you guys please look and see why this keeps happening? Its not my internet, I have tried on ADSL as well as 3G.<br> <br> Its so frustrating. Why have the facility if it barely works!
