Gmr Delhi Airport — Lost Phone Oneplus 8 with purple back cover

Dear Sir/Madam,
I am Yeon Jong Yang, South Korean.
I am a civil engineer and worked in Lucknow for Lucknow metro rail construction during 4 years
Myself and my family departed Delhi airport via Asiana Airline (OZ7683) on 26 Dec 2020 04:50am
My wife lost smart phone(one plus 8, phone no. [protected], airtel sim no. [protected]) in international departure gate no.9 Terminal 3
I heard Apollo Pharmacy store staff(phone no [protected]), store located in duty free in international terminal 3, handed over phone to no.9 departure gate staff(Mr. MOHAN Upadhyay AIR INDIA Manager, Asiana airline, Delhi to Seoul/Inchon) around 03:30am, 26. Dec. 2020 after my wife ride Asiana airplane.
But phone was not conveyed to my wife, still phone location is not clear. Apollo staff tried many time to meet Mr.Mohan again but failed. Please help me. Mr. Mohan is staff of Asiana Airline(I guess).
My wife phone have many pictures of Indian living and Kids’s school pictures, it is all of Indian memory and very important. She is student of BBAU(Babasaheb Bhimrao Ambedkar University), Lucknow, she should contact Indian professor during Korea staying. Please find my wife phone as soon as possible.
Myself and My wife stay in Korea now, please contact my Indian person Mr.Vinay(+[protected] instead of me.
Thanks and Regards
