Just witnessed a multinational SaaS provider basically telling their customer to go fuck themselves until morning because they couldn't figure out what broke their system during a production incident. Rude, unprofessional and incompetent.

Their on-call had never worked on this type of system, their network engineers didn't understand their own setup, 2nd level support randomly invented theories that supposedly explained how the customer broke their SaaS, they misconstrued everything we told them to help with debugging to then lie in their final statement for the day.

I'm speechless.

I'll not give names or details for obvious reasons.
