Big Basket - Internal damaged product received after raising up the return request the faulty product was not pic

I have ordered taking cactus from big basket on **th dec **** upon receiving the product I tried to turn it on ,But the product was not turning on I tried to charge it but it was not charging.
So I have raised a return request for the product.
The return request was raised and the guy should have picked up the return product on **th dec **** ,but on **th the return was not picked up.
Then I tried to mail them & call them they ensured the the return will be picked up but the return was not picked up.
Today is **st dec still the return order is not picked up and no response is given by big basket team
