Address:

92404

I have dispatched a packet from dtdc dwarka branch - india on 13 july 2017 consignment no. N98103015 which is not being delivered to customer and the shipment tracking history claims that the there is no one available at home but thats not true. The customer was available at the residence at that very movement.
Please look into the matter and deliver the courier as soon as possible..
