Ask HN: My GCP Account Has been Hacked What do I do?

I have had a number of GCP accounts over the past 5 years, but this last month I have appeared to have been hacked. As a result there are resources that I cannot remove that Google Support refuses to help with. What do I do? This hacker has run up a very large bill, and I do not have the resources to pay it. It would be crazy to me that I would be the first person to run into this issue so advice is welcome.
