Hi. I am sorry about this issue. Can you email dane@cloudflare.com, and it will get resolved? I am also working on more systematic fixes for when customers get into this situation.

I can't change the domain without contacting their support or paying another $2400. When I open a support ticket, their portal shows 'Unable to find your account' and tells me to open another support request for it.
All support tickets are closed automatically by their "AI" which points to the same article that says open a ticket.
Is shaming them on Twitter my only option left?
