Indigo Airlines — Complain for damage of suitcase by Indigo staff PNR no U7ZTFV

Address:

560036

On 5th September 2016 I had travelled with my sister from Chandigarh to Bangalore (PNR no U7ZTFV). I was carrying a VIP suitcase and given for check-in baggage as fragile item because the suitcase was containing laptop and glass items. When collected from Bangalore airport, I found that, the suitcase was toured, damaged. Immediately I had made a complain in customer care in Indigo. The complain was taken by Mr. Karthik (who was available on duty at that time). He told that, I will receive a call from concern team (who sits in Delhi) within 2 days but till now I had not received any call from your side. Yesterday again I called to Mr. Karthik to know the status, but did not received any proper answer because he does not know the information.
What is the problem ? Why I am not getting call ? Is there any timeline by when you have to close any complain ? If yes then what is the timeline ?
I want the complete compensation. The suitcase was costing Rs. 5400/- and purchased on 15th August 2016 only. If required I can send the bill also.
I want the compensation within 3 working days. If you are still not responding I will go to consumer court immediately.
Waiting for your cooperation in this regard.
