Horror exp of a investor with a famous broker

The following article by moneylife is missing some more information according to me.

How come a institution like kotak securities do this? I suspect the investor Ganesh would have agreed to trade in f&o seduced by the assurance of his advisor

Even then would it be possible to trade in his account? @siva @nithin

I’ve been looking for a second broker & this is precisely the reason why I’ve not considered Kotak/Motilal for that purpose. Still find it strange that people are sticking with Karvy despite them literally transferring clients money into their account.
Zerodha has things to improve, but as long as something like this doesn’t come up and they are transparent, I’ll stick with them.
