Non-Delivery of One Pair of Curtains – Flipkart

I placed an order for 9 pairs of curtains on Flipkart. The order was dispatched in multiple shipments and delivered on different dates. After receiving and collecting all the shipments, I checked the total quantity and discovered that one pink pair of curtains was missing. Specifically, one shipment was recorded by Flipkart as containing two pairs of curtains. However, I physically received only one pair from that shipment. At the time of delivery, I was at work. The delivery partner called me and requested the OTP, explaining that he would leave the parcel at a local shop in my village. I trusted him and shared the OTP. I collected the parcel later but did not immediately check the quantity because I was unaware that two pairs were supposed to be included. After calculating the complete order, I discovered the shortage. I contacted Flipkart customer support and requested a refund for the missing pair. However, Flipkart refused, stating that all items had been delivered because the delivery OTP was shared. I have already received refunds for two separately cancelled pairs. My present complaint concerns one additional pair that I have never physically received. I request an investigation into the shipment records and a refund for the missing pair. Despite contacting customer support, my issue remains unresolved.
