Air India — Loss of iPhone 7

Address:	Karimnagar, Andhra Pradesh, 505215
Website:	air india

I travelled through Air India from EWR to HYD.
When I was trying to check in the two bags at CSI(Bombay Airport) only one of them was there and the other was missing. The people near Air India information desk raised a complaint (File number: BOMAI25288) and told me that the badge would be sent to my home address directly.
Today I received my bag only to find my new iPhone 7 to be lost. Attached is the invoice for the iPhone that I recently purchased. Its a new phone (jet black 128 GB) and I kept it along with the whole box.
Also there is no mark of opening of the lock and also there is no recipe from the checking department, but they did check as the covers of the soaps that I brought were distorted.

Hence, I kindly request into this matter as it costed me 800$ which I worked very hard to earn and would be a bad remark even on your airlines.
