I lost my iPhone 13pro in a yellow and blue case.

[Yulia Kulynych]

On the home screen, against the background of the Ukrainian coat of arms, my name was indicated: YULIYA KULYNYCH, the name and address of my campsite: KURENIVKA 9:15E. I saw my phone in Lost&Found list online and left a report, after which the phone disappeared from the list, but I did not receive any response.
Where should I contact to get my phone?
I live in Orange County (Southern California). My phone number is 9494265836 and email: [email protected]
