DTDC Courier & Cargo — excess delay in shipment

My courier was booked on 29th May from Faridabad and it was received at hub on 1st june in Hyderabad. It was received on facility, Hyderabad at 6th June. Now, it is 12th June and my customer has not received it in Hyderabad so far. I contacted the contact person, DTDC in Hyderabad and he told me that he go to office only after 3PM and was not also polite with me. He asked me to complain about the same on customer care. He told me that there is no vehicle to dispatch the material and he has complained about the same to his corporate peoples. I have sent that courier to my big client, a well known pvt. ltd. company in hyderabad there and this will create a very negative impact on my company reputation. Docket number is D49947007. Please dispatch it as soon as possible so that we can use DTDC in future with confidence.
