Accidentally closed my PSN account and now I can't reach support

I accidentally closed my own PlayStation account when I was actually trying to delete the child account.

I then received an email saying that the account won't be permanently closed for 30 days and that I can contact support within those 30 days to cancel the closure.

The problem is that my account is now closed, so I can't log in to contact support. I'm having to use another account instead.

The chatbot keeps saying it will connect me to an agent, but then I either get:

or:

This has been happening for days. I literally cannot get through to an actual agent. The chatbot just keeps sending me back to the same options.

What I find really frustrating is that PlayStation says you can contact them within those 30 days to cancel the account closure, but once your account is closed, there doesn't seem to be a proper way to actually reach support.

Has anyone experienced this before and managed to get their account restored?
