Not even an authorization from my credit card, not an email, not a denial......... Just nothing but a timestamp in my transaction log.
I believe they actually tell you right away if the CC transaction did not go through. It is my understanding they will try to charge your CC right away to make sure the CC # is valid and will allow the transaction to authorize.
The only explanation to this would be that you attempted the transaction in the middle of the night (for circle) and they will process it when their working hours resume.
