I have also had a bad experience regarding fork warranty.
Called TF tuned as was tempted to get them to do the work instead who where very helpful (and spent their time to give me advice on the problem and it was a warranty issue in their opinion) and then went direct to Fishers where Phil sorted it all out for me and I got a nice new damper assembly fitted under warranty.
But my Malt 2 was a great bike (still have the frame to sell - a bit too small in the end as I got back into riding). Although they did fit the wrong brake adapter not realising that the front and rear 160/180 are not interchangeable as the holes are off-set on shimano adapters. Small matter and I just bought a new adapter as I put it down to a mistake that was probably not helped by me changing the fork and brake spec.
