There's a hell of a lot more than 12 bucks on my card. I tried twice

Hello Frank,
Thank you for your question about charging your card. The message we have from the card processor is to call your bank. That's all the info we have.
The $12 instances you see on your card are not charges, they are temporary authorizations.
I hope this has been resolved to your satisfaction. If you have additional questions, please don't hesitate to ask.
