So disagree. Their support is 24/7, we had an issue (later turned being our mistake), their tech support was working with us overnight. Yes, it was via email, but who cares? I would not sit with them on the phone 8 hours as we were troubleshooting. Our DO bill is $1k/mo, not sure if this impacts their response time. But on the other hand, I myself run a larger SAAS, and you are just not able to help everybody fast enough, you need to prioritize and you prioritize enterprise clients.
