I recently bought some Zeel shares and found that they only paid “Dividend on Preference Shares & Part Redemption of Preference Shares” for 2020.
I wonder whether will I receive dividends in the future? If not, I have to sell it.
In that link dividend paid to preference is showing zero.
Then why they even have to mention that 
ZEEL has board meeting scheduled on 24th July where they will also be announcing Financial Results, so will get more information then.
@Mani_Kan_Dan, if you read this release to Exchange by ZEEL in 2019, you will find that dividend on Preferred Shares was announced differently to equity shares, later that year they also paid Dividend to equity shareholders.
