Flipkart — Replacement/ refund order id OD[protected]

Address:

Bangalore

Got a defective product, on 18th oct asked for replacement immediately, request was accepted and defective product was to be picked up on 21st oct. Till date neither the defective product has been taken back neither replacement product is being shipped/ sent. Neither they are refunding money. Just extending time and saying wait for 24 hrs / 48 hrs. 3 times received message from their logistics partner ekart that product will be taken today by 7 pm. Nothing is happening just harassing customer. In same period they are delivering new product by same logistics. I want my money back by 31st Oct
