Issue is still ongoing without much progress or resolution. I'm at UPS's mercy at this point as they're performing an investigation, and whether they'll accept responsibility for the lost / stolen rod.
I know the guide didn't purchase any additional insurance, so if UPS doesn't reimburse me for a new rod, it comes down to the Guide.
In addition, since I wasn't the shipper or receiver, UPS will not keep me updated regarding the status of their inquiry, despite the item in question belonging/belonged to me. Major inconvenience as I'll have to sit on hold waiting for customer service for any updates.
So... still rod-less. Will check in again when I have more information.
