DTDC Courier & Cargo — Broken parcel, no packaging done but overcharged

Address:

mumbai 400063

I ordered a self-deliver service from Bihar[college] to Mumbai[home] since I couldn't go there myself. My friend who was present there gave dtdc my cartons. I had spoken to the agent on call and asked him very specifically to package it again properly and he agreed and charged me for it. I received the packages on 12th october 2020, dtdc didn't add any packaging from their side and my cartons came as they were given to dtdc, but broken from the edges. When I spoke to the bihar dtdc staff, they said it was 75kgs, but my Mumbai staff [where i booked it from] said it was 95kg and increased the price from Rs4750 to Rs6312. Now when I called Mumbai staff for complaining, they have asked me to call the bihar staff.
* I have attached one photo[with the blue wall] of the original packaging I'd left it in. The other photos are of how I received it.
