This is basically any cloud provider by the way, not specific to Oracle. Ran into this with GCP recently. Insane experience. Pay with card. Get payment rejected by fraud team after several months of successful same amount payments on the same card and they won’t tell what the problem is. They ask for verification. Provide all sorts of verification. On the sixth attempt, send a picture of a physical card and all holds removed immediately
It’s such a perfect microcosm capturing of dealing with megacorps today. During that whole ordeal it was painfully obvious that the fraud team on the other side were telling me to recite the correct incantation to pass their filters, but they weren’t allowed to tell me what the incantation was. Only the signals they sent me and some educated guesswork were able to get me over the hurdle
