Jet Airways — baggage lost and no proper response from jet airways people

My name is dushyant, i traveled from bhopal to doha through jet airways on 9th and reached doha on 10th morning, since them i am chasing for for getting my luggage but no proper response from there side. I mailed them around 4 mails but none of them was responded by them. I have even tried to call to there customer care team as well but thew were also failed to provide me any information.
Request you to please look into this matter as i am in doha with only 2 pairs of cloths and all my cloths are lost because of the mishandling of my luggage by the airlines and no support is provided by them.
