Yes - I worked at a place which had that experience with them. Massive outage: down for weeks, data lost, etc. We paid millions for “support” and had very little to show for it. Things escalated, and their regional VP took our senior VP out to the corporate box to discuss it over football. Monday morning, word came out to stop talking about the problem where possible. A bunch of people worked nights & weekends to get it patched up but didn’t even get thanked by anyone above their immediate supervisor.
