Flipkart — Delivery of defective product and not pick

Hello team
I purchased OnePlus Nord 2t mobile phone from Flipkart
Company delivered defective product not switch on
So i raised complaint regarding issue 8 times return raised but pickup not complete no one come for pickup
All pickup cancelled by seller without any reason
I am waiting from 12 days for resulation
I already contact more then 100 times with customer care team but not responding
They provide fake information and fake promises
Very cheap service
Flipkart is worst company of earth 🌍
