interest after date of maturity?

Sorry ! but u r not eligible if the renewal of FD was not done at the time of maturity.

Usually banks provide the rollover fascility, and pay interest for the rollover period, ar the prevailing rates .

However in your case,you may visit the concerned bank, and ask for the fate.

You can try to find out the rules from the Bank's website.

The bank shall pay the interest as per the rules and policies.

Did you change your address during this period.

Did you receive any communication from the bank during this period.
