DTDC Courier & Cargo — regarding courier

Address:

West Godavari, Andhra Pradesh, 534005

I had a very vad experience with the service.
They dont even respond for calls
I did not get my courier delivered.
When i asked for the same, they said that they wont deliver and that i should come to their office and pick up.
How can they be so irresponsible.
And they are very rash on phone.
And when i went for collecting it they charged me extra money for delivering it.
I had to give the money because it was an urgent courier.
