DTDC Courier & Cargo — product not delivered, no proper response from customer care about courier location misplaced or lost

Address:

Bangalore, Karnataka

It's been 10days i have not received the courier. And customer care is very careless they just tell we donno and will look into it. It was dispatched on 17 dec, after 18dec there is no update at all. Now it's been 4 days after raising a ticket, still not even a single step taken on it.
I have called multiple times to customer no proper response, every time its same response we need time.
Still i don't have proper clarification whether my courier is there or lost. And they are not even ready to refund. And its been already 10days were it should have actually been delivered in 3days. And dtdc courier waste customer care. They is no dedicated people also to take care of complaints.
As it was a online shopping i lost both product and money.
