DTDC Courier & Cargo — Document courier submitted on 21 Feb- still not delivered

We Dr. Reddy's team had sent courier documents from our Miyapur unit to Vizag FTO 7 unit, Duvada. As these was important document we had requested express courier. DTDC team confirmed to our Admin team that, courier will be delivered in 3 days before audit at site. but DTDC complete failed to deliver before audit, we tried to investigate but there was not at all proper communication from DTDC. Tracking details were not at all in line with actual status. When our person personally checked with Vizag DTDC team then DTDC people stated digging and addressing issue. Further one DTDC person committed that courier will be delivered immediately after audit, BUT till TODAY 23MARCH courier is not delivered. When asked to DTDC delivery person of Duvada area, very arrogantly he replied that security not allowed to deliver. so it is returned. As per practise he should have contacted one of contact person for clearance. Very very poor service and no etticuates of talking to client who is paying for service. We are having corporate contract for courier service which now definitely will be needs to reconsider.
