In my experience it takes azure support over a week to answer any question. Unless the question happens to be which person without a substantial update is taking over the case. You’ll get lots and lots of those answers.
Azure forced me onto invoice billing against my will - and every month without fail they don't automatically match my payment and I have to endure increasingly threatening emails that my account is pending termination while their support takes days to reply to my tickets about it, and when they do reply the advice is usually just 'wait a little longer'.
I've moved critical services off Azure because the risk of wrongful termination is just too high.
Someone else's computer has been painful and very expensive for our organisation so far. Escalating costs aren't even the worst problem.
Wrote to support, explained my situation, and they removed the bill without any hassle.
