Yes, as long as you bought it new, it should be covered under warranty. Only get mad if the shop won't service it under warranty, and if they won't, find another Raleigh dealer for warranty service.
The shop won't bend the bar back into shape, they will replace faulty parts. It may take a week or two, or they may have parts on hand to service it within a few days.
Show up in person, with the bike, and talk things over reasonably with the shop.
