Being a former delivery driver and seeing first hand what happens to all of these boxes I would not be suprised if it happens in transit. The driver is supposed to log when a package is damaged when they recieve it and drop it off at the house. If there is no log of damage from when the package was picked up then you may have something to go on with UPS. If it was logged as damaged when it was picked up you will most likely not have any luck with UPS and would have to go the other route.
