Unfortunately, yet just another story like this. One of these unexpected usage charges in the thousands appears every month, and with the same automatic denied too. This is one of the reasons I just stopped using these kinds of pay-per-usage cloud services long ago. At best, I still use services that have hard-bounded usage limits, like EC2 from AWS, where one instance can never go beyond 24h/day usage and is always capped, with shutdowns when exceeded, and limited credit cards, too.

It's super frustrating that this is the only option to realistically deal with this issue, since all stories end up the same way: The cloud company just saying "f* you, we don't care, pay up." and legal fees are always expensive :(
