Infrastructure Development Finance Company [IDFC] — Redemption amount of IDFC tranche 2 - pending

I have been chasing for redemption of the IDFC trance 2 bonds for last 2 months,

1. First they told Cheque has been dispatched.
2. Later they told it has returned and I should fill the details in link.
3. Details was provided but no response.
4. Then I was told to write to einward.[protected]@kfintech.com ...We just get automated standard response there.
5. After trying several times... I was told by Toll free number customer care to write to ganeswararao.[protected]@kfintech.com .
6. One week...still no response.

If dial the toll free...it takes 10 mins to get to talk to someone...
press...this and press that...

finally call gets hanged.

Folio number is - IDB0307599

Regards,
Super frustrated customer ...
