This is in regard the delivery of a courier that i have being harrased for over almost a month since my very important document has not yet being delivered through your dtdc courier service, neither it has been returned back. I raised a ticket regarding this and the ticket no. Is 2827584. The consignment no. Is k15616472 which was supposed to be delivered at godda (Jharkand), booking date was 4th october'18. On 21st oct'18 when i checked it online, the status was showing as undelivered as area is non-serveceable. I had to visit the office to enquire about the status and they said they would again send it. After 2-3 days, status was showing as delivered but it didnot reach the concerned person. Since 21st oct i am visiting your office almost everyday and everytime i raise a ticket with the website, they close it showing it as resolved. Kindly return my document if it cannot be delivered to the said destination.
I need my document back or deliver it at the mentioned address. Kindly take the necessary actions as soon as possible.
