I had that happen through some other web sites. They're just doing their job. Don't forget it's an overseas company.

It sounded an alarm because CCBill is located outside the US.  If you rarely, if ever, use your CC outside the US, then that transaction appears suspiciously out of character and triggers a fraud alert.  Actually it's a good thing and shows that your CC company is looking out for you.

But this is not part of their plan.  Happens to me everytime I renew. Just gotta pick a safe time to take action so no one else answers your phone.
