Stolen iPhone 15 during delivery

I ordered an iPhone 15 from Xfinity that was shipped through FedEx. It was delivered but upon opening, we discovered new phone missing and replaced with an old beat up phone. Phone was a birthday present for our daughter so box was not opened for two weeks. Xfinity has denied claim; have submitted a claim with FedEx. Do I also file claim with Apple? I’m now stuck paying $1229 for a phone I never received.
