Uber India — lost phone oneplus 6t mclaren edition

Address:

Mumbai City, Maharashtra, 400055

I ordered a cab from st regis on 16/03/2019 around 3:48 am. The ride was till my residence in santacruz east. I got into the cab at 4:05 am. The ride took approximately 18 minutes, the ride ended at 4:24 am. The uber which was booked was with lovesh. The car registration number is not mh 04 ju 2395. The driver has been driving for 1 month now according to his profile and has a rating of 3.77*

I forgot the phone in the cab. I got home and realised and immediately called the phone up. The cab guy answered and he quickly hung up the call. I tracked the phone on find device for google. It showed it was moving and suddenly it was turned off. According to both, google maps & find device it showed that the last time my phone was online at 4:27 am.
I spoke to the driver in the morning and he said he hasn't found a phone in the car, but i clearly spoke to him in the night.

I contacted uber and they said they have spoken to the driver and no phone was found. I have registered a complaint with santacruz police station. I am in the process to take legal action and uber has not given me any details of the driver to deliver the notice.

I lost a oneplus 6t mclaren limited edition.

Please help.
