DTDC — about my courier not delivered

Dear concern,

My courier which is supposed to be delivered to mathura on 16th nov. Consignment no. Z68563140 is still not delivered and it has to be delivered by the company. Now the executive is telling me that it has not delivered as they don't have branch their. This is a complete loss for me as the last date is already reached. This is totally unprofessional and above it they are saying they can not do anything
