On the day of 15.08.2024., while on familiy vacation in Soma Bay in Safaga City in the resort Caribian World, I was on a boat trip to Utopia organised by Fun Trip Travel agency. While returning to resort, me and my family were on the back of the bus with 2 other tourist sitting in the front of the bus behind driver. My android phone dropped on the bus, we left the bus, realised the phone was missing and immediately informed agent that was asigned to us by our local agency, who did everything to inform the company about the lost phone. The driver of the bus in which the phone dropped is egyptian, has blue eyes and is in his late 50's. We returned from the trip to our hotel around 18.00 - 18.30. We tried to locate the phone and call the number by Viber. The phone was connected to network, internet and ringing, but we lost connection with the phone around 22.00. I complain about Fun Trip Travel Agency's not existing lost / found policy. We paid and we expect safety on the trip, which includes safety while we are returning to resort tired from the trip, with towels and snorkeling equipement with two minors. I would expect they returned my phone like any other thing I lose on the boat or the bus.
