The Redeemable Cumulative Preference Shares is clearly on contract stated when redeem, must be obligated? or there is a choice to redeem after 5 years?
Or apa pun tak da, just mutually agreed verbally?

Trying to understand more first... after you 'invested' in, did u perform SSM search and check if the company did really lodge the preference shares with SSM, also reflected these shares in their Balance Sheet?
Coz if yes, then is more to company unable to fulfill the requirement of redemption.
If no... means ur money is dump into salt water sea

Correct me if i am wrong, coz this is wat i understand about preference shares

Not u lodge, but the company/company sec...
If u wan go legal, u also have to find out this matter first btw

Hmm... just simple go CTOS or eSSM, pay few ten ringgit and u can get it. But only if u know how to read it (not complicated, but at least need understand).
But anyhow, like above say, its RM2.0 mil, think u wont mind payment few extra hundreds to get a lawyer to do for u, at least they help u go in details.
