Infrastructure Development Finance Company [IDFC] — Payment of redemption of IDFC bonds not received

This is with reference to the redemption of INFRA BOND TRANCHE 2 Folio No: IDB0308866. . inspite of many requests about non receiving the amount either by bank transaction ( all bank details are provided ) and DD ( without my concurrance they replied about sending the dd ), i wish to get your immediate action .
I was surprised to get the answer from einward.[protected]@kfintech.com about the despatch of DD. even now aviral courier is showing it is not despatched to me. How can i encash without receiving the dd.
I have a great faith in this company. but now i am very much upset. This kind of fraud action to be stopped otherwise a legal action will be taken by me.
