I just got an e-mail from a Jacob Cheney, claiming he was from CZ-USA and that there was a payment issue with my current order but without an order number. Next, I went to the CZ website and signed in to my account, everything looks correct and the status is still Staging. My CC info was still current.
The phone number and extension on the e-mail matches those on the website, so maybe it is legit after all. I phoned in and was placed on hold with a wait time expected of 60 minutes, so I hung up and will try again maybe tomorrow. But this is progress!
