Sorry to hear about this Serg. It's easy to forget about the random groups that go smoothly, so the odd groups with a rude player can be hard to forget.
As the other posters have suggested, use /ignore to help protect yourself from this kind of behavior, and remember that most players will be helpful and supportive. A bit of good humor can help break the silence and grind-mentality that some people seem to bring into the random dungeon runs.
Happy adventuring!
