I have the same issue but just for Google Cloud thankfully. Never got a response when I filled in the text field. When I contacted support they kept asking me do go to things in the Google Cloud dashboard (that I was banned from). Then eventually the person said they'd escalate and I'd get an email but I never got anything. Maybe I'll try calling a sales number.
It's your sign to move on, there are hundreds of other cloud providers who will actually provide meaningful human support because they need your business unlike Google.
