How did they "blow you off"? Getting a letter from them explaining the same thing wouldn't have been any different, except that you'd be short one lure you can potentially repair yourself. Sure, if they were going to send a lure, why not a new one...but I doubt that the place you sent your lure to even has new ones lying around. Easier for them to give you your lure back....besides...damaged lures like that that get fixed up with your own creativity and ingenuity (ie. crazy glue) often make amazing comebacks with big fish.
But, your story illustrates how we are all different. I would've sent an email asking them if it'd be worth sending in for a replacement..got my answer, and busted out the crazy glue. You sent the whole lure in...and now you're bustin' out the crazy Just kidding...sorry for your loss.
