Overnite Express is giving good service with insurance facility better than DTDC. DTDC never reply to email's & if you have any wrong delivery it never resolve, if it resolve they take lots of time. Overnite replies to all emails withing 2 hours & resolve any issue through email, you no need to keep calling them on phone as we need to do it in DTDC. Overnite is giving very good pricing also if you contract with them, but their minimum charged weight is 500gm so we prefer DTDC for couriers upto 250gms & above it we give to Overnite ...
And the best in courier industry is FIRST FLIGHT .. they are doing better than BLUE DART. Delivery withing 24-48 hours. So we trying to tieup with them but they are little expensive.
So my suggestion is OVERNITE
