Track rods

The steering has always been a bit woolly, but I just thought that was how it was supposed to be. We had a recall letter – something to do with the steering, and whilst it was in, they advised us that the track rods were worn. We'd had the car for maybe 4 or 5 months. We were told that track rod ends are covered, but track rods are not. Surely they can't have worn in that time from being fine when sold to "excessively worn" a few months and 3,000 miles later?
