Amazon might be slightly better than Google with regards to finding a person to speak with, but, not any better with finding a person who can do anything when you've been wronged.
That said, it seems that "Amazon" and "AWS" have entirely separately run customer service organizations. I have no reason to believe GCP customer relationships are managed in anyway resembling the way they manage their cattle on their free services where the user is the product anyway. Why would they?
I'm certain GCP has separate support, otherwise they wouldn't be able to compete with AWS.
