ORDERED BRAND NEW APPLE WATCH AND RECIEVED IT IN TAMPERED STATE. APPLE WATCH STOLEN

I ordered a brand new apple watch series on May 15, and received a tampered package delivered via UPS on May 19, 2020. When I opened the package the apple watch was missing, and it was just the straps and charger.

I reported the issue to apple immediately. But did not receive any effective assistance so far. They keep telling me that it would take two business days. However now three days have elapsed and still no response from apple. Please help!!!
