DTDC Courier & Cargo — courier undelivered

Address:

Allahabad, Uttar Pradesh

Really fed up with the service of these dtdc unit at allahabad civil lines with contact no. [protected].
First of all they never deliver courier on time and when give a call to know the reason, never pick up the calls easily. If i make a call at least 4, 5 times then only they pick up. My courier bill is attached and you can see it's been 7 days around and still the courier is undelivered though the courier has already reached there with them in 2 days itself.
Moreover the kind of response they give over call is really mind blowing. Always talking in a rude way, really upset me.
And this is happening everytime my courier is reaching them. Kindly help me and really these guys must be punished as they are harrassing in a same way to others as well, it clearly means.
