On-Dot Couriers & Cargo — Bad service provider-non handling of customer

I have sent a courier on 27th june 2016 but till now it hasn't been delivered.
From last week, i am contacting them. earlier they said "let me to check your status but till now they are saying that it is on the way for delivery.

From yesterday i. e 11th july 2016, they are not picking my call. now, i am feeling harassed.
My consignment no.[protected].

Now, its my personal request to the concerned department to help me in this regard.


Thank you
