Quick question where did you buy them from?

Too little details. You have as in? physical bond or you hold it in demat account.
Do you know ISIN for the bond?

Otherwise only bond that matches this description are L&T infra bond of 2011.
These were cumulative bonds and matured on 23-Mar-2021. So payment should have been made 3 years back.

If you haven’t got your money back, reach out to registrar.
