Flipkart — Issue in exchange product system

Had Ordered A LG 7 Kg 4 Star Semi Automatic Top Load Grey, White (P7020NGAY) And Had Applied For Exchange Offer Of My Old Washing Machine. The Exchange Value Was Rs. 1050. However, During Delivery, The Delivery Agent Refused To Take The Product. Reason Was That The Seller (RAMTHRALLA Retail) Had Not Updated Any Details About Exchange. Flipkart Tried To Resolve The Issue, However In The End It Was Impossible Due To Seller's Mistake. My Old Washing Machine Was Not Exchanged And I Had To Pay An Amount Of Rs. 950 To Make Up The New Product. Due To Seller's Negligence In This COVID Situation, I And Other Parties Had To Face A Lot Of Inconvenience. Proper Action Must Be Taken Against The Seller.
