Indigo Airlines — Baggage handling

We have traveled on 22-jul-16 from calcutta to coimbatore/ connecting flight in channai. We did not get the bags on chennai and we got the bags on coimbatore. But our bags are damaged very bad. Not only my bag my friend bag also. Two month back also we noticed but we did not take it serious. But this time we effect badly.
Your luggage handling is very very bad and i had discuss with our office persons also they also agreed the same. Your flights are good, but due to bad luggage handling we are not satisfied your service.
It is very very bad.
