Idbi infrastructure bond 2002c
Non receppt of matured amount

I have purchased IDBI Infrastructure Bond (2002 C) on 20/3 vide their cert. No. 134071154 Dist. Nos. 0134251100 to 134251103 of Rs.20, 000. The bond is with me and not redeemed. When I contacted the IDBI Bank, they said it was already redeemed and sent to my SBBJ, Bhiwadi bank account No, .11718 on 30/11 for Rs.27, 300 but when I asked the bank, they said it was not received by them and my bank account statement shows no such credit. The bank is not responding to my mails. Pl. iintervene in the matter and get me credited the same amount to my account.
