Contrast:
Microsoft - flat out refused me more quota despite spending 10k/mo with them. Required me to convert to invoice billing, and then wanted a bunch of proof of incorporation and when my trading name didn't match my registration name they were unable to proceed.
Oracle - took 3 months of escalations and deliberations, required me to explain on the phone to a VP why I needed the quota.
AWS - frequently requiring me to write up a spiel about what I'm going to do with the quota before they approve it, increasing the RTT to 72hrs+ - do they actually verify this? How would they? Why do they care so much? We've spent 50k+ and always paid the bills, what's the issue?
