First Flight Courier — Bank consignment not received but updated as Delivered in Firstflight courier portal

Address:

Bangalore, Karnataka

One of my consignments from HDFC bank was not delivered although your website says that consignment is delivered successfully. Consignment # C[protected] It was mentioned that the consignment delivered to a person called Saravana. First of all, 1. I didn't receive any call from the courier person. 2. I spoke customer care and they claim that the courier might have went to bank directly. But as per the bank, the consignment has been sent to my residential address only. 3. How do i get my consignment back now? I would like to lodge a complaint on Firstflight in this regard since those documents are very important.
