Air India — Lost Iphone 8 Plus

Myself and my family (4ppl)was traveling from Kochi to Dubai on AirIndia flight AI933 on 7/03/21 and left behind my phone on the pouch of my seat 27B, my family was allocated seats from 27 A to 27D. I have enquired in dubai airport and in the Air India office. The air India officer had adviced to send the email to [protected]@airindia.in and its is giving a bounce response, showing undelivered. The same flight had board in Mumbai airport the next .When we wrote mail to mumbai team on this they says it is not found, but i am very sure that it will be in the pouch which was infront of my seat.The phone I lost is iphone 8plus with a black boarder cover and transparent back. The chance might be the cleaners not noticed my phone in the pouch while they cleaned the seat I was in.
Could you please consider this email and help me in getting a right response. Appreciate your help and time.
