It seems no one is buying anything from GCC?

I tried to place order(s) at GCC. But all order got cancelled right away. They did not even go through card charges. Every time, GCC sent email,

We had to cancel your order #xxxxx because it didn’t pass our screening process. Online security is important—like really important—so we take every measure we can to protect the people shopping with us.

We suggest you check out your billing and shipping info—there might be an oopsie in there that needs fixing!

Please note, no funds will be collected from the payment method used for this order*.

I had no problem placing orders before. I have a couple accounts. I also tried to use guest account. Also changed credit card.

I searched online. Some people have the same problem. They had to create a new account. I created a new account before and order went through. Just wonder if there is anything else than new account.
