I tried out a 30 day trial of Oracle Cloud, decided it would work for my needs for a new company I'm starting. When it came time to upgrade my account to the paid version, the payment verification failed (I tried multiple times with multiple different cards, they must have blacklisted me).
Anyway, thinking it was an error, I tried chatting the support: https://i.imgur.com/dlf2wQP.png (you need a paid account to chat with support, even if you want to chat about paying for your account)
Then I tried emailing to see if they could assist: https://i.imgur.com/T9jkKx7.png
I guess this is the type of customer service Oracle provides for customers trying to pay them money (only around $300/month to start, maybe not enterprise enough for Oracle).
Decided with that last email reply that it's not worth starting a new company on Oracle Cloud platform if this is the type of response you get from support.
Oh well, back to AWS I go!
