Tata Cliq — defective product. initiated return. item not picked for return request

Address:

Pune, Maharashtra, 411045

I had ordered Kent Maxx 7L UF Membrane Water Purifier on May 30th.
I received my order on 9th June.
On the next day the technician came for installation and he mentioned that the product is defective.
So I Raised a complaint on 10th June Complaint #[protected].
Customer care representative mentioned me while raising the complaint that this complaint will be considered as official return request and I don't need to initiate any return request. But I didn't receive any response for the complaint for 5 days.
So i myself triggered a return request online on 15th June.
It's been around 13 days since I have triggered a return request but still the product is not picked up from my address
