Delhivery — I got a wrong package when shipped from Bangalore to Hyderabad.

I had shipped a black bag along with a couple more bags and a carton box from Bangalore to Hyderabad. It happened sometime end of March. All the materials have been received except for the black bag, Instead i got a white carton. I filed a ticket saying i got the wrong bag delivered. But there hasn't been any response from the team and it's been close to 1.5 months now. I have sent the video and images of the item i have received as requested, but they didn't bother with it at all.
