Flipkart — OD[protected] Damaged Product Delivered

I ordered 4 chairs on 13May which was delivered in broken state on 22May.
Immediately within 10 mins of delivery I raised replacement request.
The return was approved by your technician post verification of product. However, your logistics team refused to pick it up.
I complained to customer care but of no use, my 4 returns were rejected due to refusal of pickup. I spent so much time in complaining to your team but no resolution.
Each time your team places replacement request, your logistics partner refuses pickup.
It has been almost 10 days and i am still looking for a resolution.
I am looking forward to Refund now but that is not getting processed.
