Not sure if you have any recourse with UPS. it was obviously packed minimally, and UPS as do all shippers say double box, with a minimum of 4-6 inches of shock absorbing material on around all 6 sides. When someone does not do this, the shipper says it is not their fault. Wonder if you bought this from a ham site, QRZ, QTH, etc? Post the seller's call and name on the complaint page and shame him.
My famous shipper fails, a Palstar tuner that was shipped in all its original packing via FedEx, dropped from a height by someone in transit, and the impact caused every single item that was mounted on a standoff to break. They refunded the cost of the tuner but only half of the $60 shipping. The other, an Icom rig sent to me for repairs, arrived with a set of dual wheel tire tracks across the box, flattening it, and UPS said I did it. They eventually paid the owner for his loss, but it was a heck of a battle.
I think when you ship anything today, call Vegas and get a line started on it to see what the odds are that it will arrive intact.
