Infrastructure Development Finance Company [IDFC] — IDFC Bond - Redemption Scam

I have invested on IDFC Long Term Infrastructure Bonds - Tranche 2 which is matured at 31 Dec 2021.

Folio No.: IDD0276707
BondHolder: Sumit Kumar
No. of bonds: 4

During July 2022, I saw the bond certificate and realized that bonds had matured on December 31 2021, and hence reached out to Kfintech for redemption. They mentioned that bonds are already redempted,
They have used some unknown courier service (aviral courier) to deliver redemption bond which were never sent to customers and those courier service marked the consignment as delivered in their system.
