DTDC Courier & Cargo — complaint regarding gas stove - damaged parcel received

Address:

411008

It's been 10 days, I have sent this mail to Akash - Manager at DTDC Aundh Pune there is no response from him.
Over the phone he said that DTDC doesn't courier glass material (gas stove) but previously his colleagues (DTDC employees) accepted the courier and they delivered the stove in pieces. Which you can see in attached pictures. That new gas stove is completely broken and we can't use it at all.

I have raised this complaint to the customer service representative and we have visited DTDC Aundh office as well but there's no action and these guys are least interested in addressing the issue.
