I had purchased a product from Amazon (Or der No:[protected]and received on 12th Dec. Due to product issue I had requested for refund on 12th dec and pickup scheduled for 13th dec and from that day till now pickup has been rescheduled 6-7 times and no one coming for pickup. I tried calling the pick up agent ([protected]) and he asked me to wait for on hour and he is on the way and coming. I postponed my plan and waited but he did not come and when I called him again he did not respond and switched of his mobile. Can you tell me whether you can refund the product of not. Give me one date and one time for pickup.
