Err, I don't know the rest, as the only time I did that was when my credit card company (possibly of more sound mind than me) thought I was buying too many tickets at once and it raised a fraud alert on the purchases. This is when I would see a handful of shows in a week, etc., and happened to book them all at once... so I called the credit card company, approved the transactions, and then called Telecharge and they reprocessed the orders and that was that.
