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 is…
That was really all I had: expressions of astonishment at the prevalence of Google apologist comments here today.
In an effort to be constructive let me say, it's a matter of scale. Google can't be fair because of their scale. Contrariwise, I use small-scale services and get outstanding customer service.
E.g. Tarsnap, cperciva is a god among men when it comes to customer service. Or sr.ht (Sourcehut) ddevault is right there on IRC most days. Or Podia, I wanted a certain font on my site, they didn't have it, I emailed them about it and they literally added it within the hour. Give these folks your money, eh?
