Hate to say I told you this would happen in the other thread. Very typical of UPS. This is a problem as they are self insured.
If the driver told you the package was f'd up at the depot and told to deliver it by mgmt., get it in writing from him if possible.
Tell the UPS claims manager that you will be heading to small claims and all the local TV stations/news outlets if this isn't handled in a professional manner.
Stay after them. Those F'ing turds make collecting as difficult as possible on claims.
