Completely. I will say amazon is usually very good about refunding money if you made a mistake or got hacked so in that sense their customer service is pretty good.
One time we had literally 1 million cloudwatch metrics get created because we were monitoring mongodb databases and a CPAN test was creating test DBs and not deleting them and we were not ignoring dbs created with names like test_* when creating the metrics.
Another time an outside developer committed a root credential on a public repo in github to a (basically) unused amazon account.
Both times they refunded the costs. Not sure if that was because we were paying tens of thousands a month though to get this service though!
