I know I'm going to come off as a Google apologist, however, I'm leaning towards there being more to the story than what you are saying.
The previous month's billing didn't 'went through' and you are unable to zero in on whether this is a Google issue or a you issue.
I get that it is easier to complain on the internet and often cathartic do so as a coping mechanism.
Having an account suspended because of a billing issue is not exclusive to Google.
Have you moved your projects off GCP now as voting with your wallet would be the sensible thing to do. Until you encounter a billing issue with AWS and move again to Azure and then to DO.
