You sound very close minded Antix. Maybe people just sound rude and stupid to you because they are frustrated from being treated like cattle at a crowded feed trough after waiting 20 to 60 minutes to talk to an uncareing tech support who's only thrill anymore is collecting their paycheck. Perhaps you are just not cutout for this job. :t
Well, they make it obvious that they are, so it's their own fault that something screwed up, not the companies. They can curse all they want, it results in a disconnection of the call, and in most situations, a refusal of service.
