[Resolved]  Trackon Couriers — non delivery by trackon couriers

My pancard was sent by nsdl through trackon couriers on 2nd nov, 2019 and i am yet to receive it. Received an sms that the delivery date is 11th nov, 2019 (Is this really a courier service? 10 days for a cover to be delivered from mumbai to chennai?) the tracking status was "out for delivery" on 5th nov. Expected the delivery on 5th or 6th nov. But, it didn't happen. Thought, the delivery would be done only on 11th, as per the sms. But, on 9th, the status was changed as r. T. O due to door lock. 9th, i was out for a couple of hours and was checking the cctv to see if i get it delivered, while am out. Neither did i receive a call nor i could find any footage in my cctv that they tried to deliver.
Called customer care and asked why wasn't i called on my mobile. And the answer was, your mobile was out of coverage area, which was as well impossible. When asked what could be done they said, if it is in chennai, we will try to deliver else, you need to co-ordinate with mumbai nsdl. How would i know where the courier is? When asked, there was no proper response. Haven't received the card yet.
Not sure why nsdl ties up with such guys, who are cheating, without even trying to deliver? Our indian postal service is far better than these guys.
Not sure, if i could get my pancard on hand.
