Indigo Airlines — My luggage gone missing since three days

Address: Ahmedabad, Gujarat, 382421

My name is shah rutvikkumar pinakinbhai and i travelled through indigo airlines from delhi to ahmedabad on 7th november fligh number : 6e 597 on 9:40 pm.
When i landed to ahmedabad to my great surpise only my baggage was missing since that day. My bag and things inside are not only costly but connected to my heart too.

It has weight of 17 kgs and purple color american tourister bag.

Taff is not handling this case in a good way one person is saying we are tracking your bag, one person is saying your bag is in delhi send us authority letter and aadhar card which i already sent on two different whatsapp numbers as demanded. One person is saying your bag is being delivered. So, i have left with no clue. If i wont get my bag today only then i wil left with no option to complaint in police, press and media.
