Sometime,i guess there is technical issue while transfer a money from demat account to bank account.And second executives of zerodha.com don.t have knowledge about stock market.whenever I ask them about any shares or and any segment,so most of the time,they provide me ashlata narvekar no,when I call on her no.so she directly shout me over my face,she thing I am trying to propose her,she say directly don,t call me,if want to know anything,please send me message on my mail.
