- This is not a UPS site. You will get a lot of opinions here but no one on here is actively going to do anything in terms of looking for the package
- You did not pay for the shipping. UPS only deals with the company/person that paid for the shipping for any claims.
- You said the company sent you the ring so they know everything about it in terms of a description so if it is actually in UPS over goods and the company gives a good description, it will be found
- You need to deal with the company that sent you the prepaid label
Once again, if the company that sent you the label inquires with UPS to report a missing package, the first thing UPS will ask for is a tracking #. If the tracking # shows never being scanned, that's going to be a major hurdle to overcome in terms of a claim. For a claim to be paid, there has to be proof of UPS actually picking up the package. Overgoods can always be searched based on a description of the goods but again, that is for the company that paid for your return label to initiate and pursue.
My advice to you - if you think this was stolen, file a police report. Do you have homeowners or renters insurance? If so, file a claim with them.
