Trackon Couriers — Pancard non delivery

My Pancard from NSDL which reached TRACKON Perungudi sub office in Chennai for delivery on 22.1.22, but not delivered till date.Complaints raised twice with their corporate office, and they enquire and tell us Packed deliveed and signature obtained. This is utter flase information, as our complex enters every service visitor and others at Gate with Book entry and CC camera, which I have checked from 20.1.22. We raised complaint with NSDL at Chennai two days back and they returned saying helpless and we should contact Trackon. Please resolve this issue as a responsible Big Courier cant lie and get away with such excuses and they should be made accountable . I see in complaint register, with NSDL, many have complained similarly. Thank you.
