Flipkart — Delivery of damage product and not pick

Hello team I am purchased OnePlus Nord 2t mobile phone from Flipkart at 21 September order no-OD[protected] company delivered dead mobile not working condition
So i contact multiple times regarding return this product
I already file 3time complaint at national consumer helpline portal regarding this issue
Company create 3 Times return request regarding this defective product but every time seller canceled my return request
Today 18 days already complete but product not pick yet
Very cheap service
I already contact multiple times with Flipkart customer support but company not responding they provide fake information
