DTDC Courier & Cargo — late delivery

Due to an urgency, i posted my parcel through the air.in spite of sending it through the air, it took almost a week to reach it and it was then useless.

Dispatch city: rajkot - on 29th january
Dispatch code: d57157716
Postal city: bengaluru, karnataka - 562125.

It was an urgency for the parcel to reach. And that is why in spite of the high costs, i choose to send it by air. The parcel was of 4kg and due to its height and volume and don't know about the company rules, i was charged the prices of 11kg. So, in total, the parcel went for rs. 1540. And then also the purpose was not served as it didn't reach on time. I tried several calls, but on 31st january none of my calls were received at rajkot office.

And then today - on the 4th of february when i made several calls, the parcel reached. The tracking system is showing that the person went to give the parcel but the customer didn't receive it. And the truth is that even the person from bengaluru tried various calls to ask for the same that why are they not receiving the parcel if it was already at the airport since 30th january evening. Even the person from bengaluru who was supposed to get the parcel asked if they can directly receive it themselves from some warehouse or anything like that, but nothing was answered clearly.

I need a refund for the same, as i put so much money in shipping the thing but due to the lethargic delivery, the purpose of shipping was not served.

I need a quick response to this.
