I have given one star as ther is no option for less than that, they have worst customer care . Recently I had an issue with my holdings(average uy rate was increased for many of my holdings), I am calling them from last 2 weeks, raised tickets but no resolution and after this when I am calling them their customer care went into argument mode and was too unprofessional. I am really done with Zerodha, I am going to reduce my holdings from here .
