Blue Dart Express — Product Not delivered but marked as delivered

Totally disappointed with your service. Never gonna use your cargo service again. I have couriered one product using bluedart and the shipment is showing as delivered. But when i spoke with the recipient they told they haven't received the product So when i tried to download proof of delivery there is no image present in the tracking link. And customer support is also not helping in getting POD. I need POD right now else bluedart has to pay the whole money. Such a bad service
