DTDC Courier & Cargo — consignment no : b53946879 not delivered and returned back by dtdc

Address:

Bangalore, Karnataka

Hi

I had booked courier no - b53946879 via dtdc on 14th june and now after a week, they are saying it could not be delivered.

Online status shows that airport security didn't allow it to board but i had clearly told the booking agent that it's a powerbank and still they booked it.

I want the full refund for this order since it's their fault but they are not responding at all
