I've been watching this thread with a sense of curiosity. Being in the food service industry I've been on both sides of poor service issues. so here's my 2 cents.
write off UPS. the guise/shop screwed up on the shipping and the rod is gone. Look on the bright side. someone stole a broken rod. if they get caught it was for stealing broken stuff. kind of a Karma thing.
send a certified letter to the shop and also the same in an e mail. state what you want to settle this. you want a new rod of the same model or better. Plus since the guide screwed up your trip by having the wrong equipment and for his lack of care in yours you want a free guided trip replace the one you planned on.
also in your email to the shop reinforce the fact that if the issue is not settled in X number of days you will be posting your experience and naming names on every social media site and fly fishing related board possible.
I would bet that by going this route your issue will settled in less than 24 hrs.
It's worked for me, several times.
