You are actually doing this wrong...
Report to the national authority first...
Then report to Google.
Fuck them, it is not in your interest to report to them first, make them react for their bullshit. Over here in the states this is how I ended up dealing with telecom in the ISP industry. "Hello, I have put in an FTC/FCC complaint on $issue, and would like to see about getting it resolved".
It didn't matter that's not the order you're supposed to go in, at the telecom side they send it off to a team that actually gets shit solved before it becomes a regulatory problem.
You might have a stronger case with the national authority if you first do the full "trail" of reporting, appealing, and eventually escalating.
But yes, I feel that there's something wrong in having a stronger case if you first do it "gently" when they wouldn't bother if it were the other way
