Jomashop Watch stolen at the Post Office Brooklyn Internet

I bought a Bulova watch from Jomashop sometime in November and I followed up with the Post Office in my country it was reported "tampered with" and this was then reported to Jomashop. The watch was insured in transit. 

Jomashop advised that they will open a query with USPS as the shipper, and will give me a report in 3 months and I have never heard from them from then. I have been sending email to them to provide me with a report or a refund if they cannot post the ordered watch. 

I have been battling forever to get a refund if not my watch. This is really frustrating to be defrauded by so called reputable company.
