You are defending them. Unless OP is disingenuous, the reputational loss of an unhappy customer is hard to shake. Customers will make mistakes, if the cloud provider doesn't have automated systems to catch and prevent those mistakes then they aren't doing well in customer service.

A similar thing happened to me with my personal Azure spend, but I felt they handled it much better simply by communicating early and often when there was a problem processing payment. I had time to respond and fix my subscription, so I stayed a happy customer.
