I recently order a mobile phone of Xiaomi Mi and according to details blue dart courier was supposed to deliver the product to my residence address and I placed my order on Cash On Delivery(COD) but after four days I received a message indicating that your product has been delivered successfully.
But I never received my delivery the Blue dart delivered my product to some other guy or they must have sold it to some other person as Mi phones have great value in the market.
Blue dart is a scam company and avoid using Blue dart services and go for some other courier services.
