Nobody cares how hard you or your coworkers work. Results matter, nothing else.
Given the story so far, you offer adwords style customer service (we don't give a damn about you) while attempting to catch up from position 3 behind aws and azure in the paas race. Complete with automated emails with outdated documentation and no human anywhere without a social media outcry. I'm sure stories like this are damaging (seriously, just use aws), and there will be some postmortem damage control, but unless I see a human support sla for situations like this, I can't see why anyone would risk their business on you.
Seriously, a fix it or we shut you down email for reasons you won't share with an 2 business day response. Of course, you're issuing a 3 day warning, so if that fell on a Friday, you would be dark before anyone bothered to look at the support ticket (3 days expire Monday, 2 biz days Tuesday evening). Amazing.
