In Google's eyes cancelling the authorisation is robbing them because they charge in advance and they might even cop a rejected payment fee.

I agree there may be no other option, I'm just warning to be ready and prepare for the possible loss of "connected" (in Google eyes) accounts.

Definitely not bullshit. I have a friend who was banned simply for returning a Pixel phone after accidentally ordering 2. Some automated mechanism flagged it as potential fraud and nothing worked to reverse the ban. Going to the bank to block payments, remove authorization, or God forbid, do a chargeback for the money they already took after banning you is playing Russian roulette with your Google account.

It's also the only way to stop Google from stealing your money short of going to a lawyer.
