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!
