Earlier quoted context omitted.
You're going to laugh, but this is why I stick with AWS. They've twice helped me with billing issues on my personal account - as in an actual human helping me. They have no idea I manage large (not huge) AWS deployments at my day job. They just demonstrate great customer service to me as a small client. So they have me as a loyal customer. And advocate, it seems.
AWS support is extremely good. I have had the same experience in personal projects and in turn have quadrupled down on our leverage of their support at my work.
It's annoying that they actually solve my problems because it would be so easy to hate them as the 900 lb gorilla.
