I booked online for tickets and an hour later, they emailed and/or called back that my CC is not authenticated. I know that's not true because I triple-checked it before clicked on Submit. Now that I called back, they said the price had been gone up almost double if I still want it. I double-check a website again and the price is still the same but this time didn't put the CC yet. That tells me that they try to steal your information and at the same time try to use the same lie again about CC does not work.
