URGENT: huge cost increase for cached content storage token hours

Hi,

I have seen a few posts around the billing issues on Google’s part, but raising this as a separate issue. We have just been sent a bill for £10,000 out of nowhere. I think it is impossible to get to that number of token hours in such a short period of time. We have raised support tickets with the Google Cloud billing team, but they said it will take up to 2-3 days for them to get back. Has anyone faced this as well and wondering if anyone had any luck resolving it.
