What information did the crew gain from their maintenance department while holding before the last approach? If you don't know, which from your comments it would seem you don't, how can you question their airmanship?
Spotters opinion really can be distracting on this forum. How you can have such forthright opinion on an event you have no understanding about, while not understanding how your aircraft behaves when conducting a missed approach. This would reflect more poorly upon yourself than this crew.
This crew had nothing to do with what the company says. They just did their job.
