IFCI — Issuance of a new cheque for matured amount of long term infrastructure bond series ii.

I purchased 4 IFCI Long Term Infrastructure Bonds Series II which has been matured on 30.01.2021 and a cheque is issued mentioning an Account No. which I shared with you at the time of purchase. But the problem is that the old Account No. is now invalid. And obviously the cheque couldn't be encashed till now.

So I would seek your guidance regarding surrender of the old cheque and issue of a new cheque with the new Account No.as early as possible.
