DTDC Courier & Cargo — deny to delivery

Address:

Amritsar, Punjab, 143001

My courier consignment no is z76237106.
Day before yesterday i got call from the dtdc that we don't have any delivery boy for your delivery and you have to visit our office to pick the order. This is very worse answer from the people in from dtdc. And then he told that if you will not pick the order from our office then we ll send it back. This is the number from where i got the call.

The same day i put the complaint in dtdc customer care and told the incident. They gave me the case number 12971861. And told me that your concern will be solved within 6 hours. But till now i didn't got any solution of my concern and courier.
Kindly put the strict action against them.
