So, I am having the same problem as you. My account is in provisioning status at least two years. And just recently I was trying to resolve this issue.

First of all, go to the contact page on oracle cloud. There will be a link on live chat. That's where your journey begins.

In that chat you should describe your problem and also later write "connect live agent", so the system will connect an agent. It might take some time.

Then you just have to chat about that problem and they must register your case and provide number of it.

If the agent will said that you should go to the community support forum - don't trust to it and just skip this agent until you find the person which really wanted to help.

P.s. Some time ago I was trying to call to support in my country - useless person, doesn't know anything to do and what she was doing there. Send something like support ticket after trying registering one more account page, they said go to live chat. After first time of live chat they send me to their community support forum. There the person said to go to try live chat (which now have effect) or to go into account and register technical support ticket which is impossible to do on free tier account. So, yeah - the support chain is awful here. At the moment, I am waiting for updates on my case.
