Fedex stole my IPhone 17E

Has Xfinity resolved similar cases? Xfinity box came empty with no phone. After 2 weeks. No real update to my case. Im thinking about getting my attorney involved after 2 more weeks if they dont help me. Its ridiculous. 8 years with this company and they want to take their sweet time in resolving this case. They know this happens a lot and I know they have insurance.
