Bluedart courier (Thirumalgiri branch) is to be sent a incoming courier to me. On arrival at my address, the delivery boy is supposed to meet me at my address and deliver the courier to me by taking a reciept signature from me.
But bluedart courier (Thirumalgiri branch), the delivery boy never visit the address and by evening they update the status of courier as "door locked" as it is a false excuse for them on online bluedart site.
Like doing this, they update my courier status for four days. I sent my colleague to bluedart courier office (Thirumalgiri branch) to enquire about the things. Where mr mohammad who is managing thiumalgiri branch, said we gave a phone call to the mobile number and he didn't answer, thats why we didn't deliver the courier and behaves very rudly manner.
As a customer i didn't expect that when a courier will come to me and to attend his call. When the delivery boy would visit my address. If i am busy at my work then how could i attend a call from unknown number.
If the delivery boy would visit my address, he make knock at my door or else he should have talk to my family or my servant, to know about my whereabouts.
Even i personally visit the courier branch to collect my very very important courier the bluedart agent mr mohammad behaves very rudly despite of being that i am a customer. He cannot handover the courier at his office, he sent to the address only.
I would bring to your notice that "bluedart courier (Thirumalgiri branch)" reviews on goggle is also very poor.
Please take action against bluedart courier (Thirumalgiri branch), as these agents are making funny with the customers.
