[Resolved]  Indigo Airlines — check in luggage missing in indigo airlines

Yesterday i travelled from mumbai to kolkata in indigo flight 6e323. I reached kolkata around 14:45 hrs.
On arrival, my check in luggage was not on belt. I registered a missing complaint.
Initially they told me that it's a case of bag exchange and they have identified the person and his bag is with the airline.
The airline staff handed me a copy of the complaint and said that they will send my bag to my address as soon as they receive it.
Today around 12:00 pm, when i called them the executive replied me that shift is changed and thats why she is not aware of my case.
Again i narrated her my story and then after sometime she confirmed the case with other staffs.
So with shift change, case is forgotten. Now customer had to remind them. Is this professional approach by indigo airlines??? I doubt.
So far i have not received my luggage and without those warm clothes i am shivering in cold.
Indigo staff says they can only keep calling that person, can't do anything more.
I have waiting helplessly.
