Worst ever customer support I had ever seen. No one picks up your calls. There is no support mail available. You have to raise ticket on support portal which will never be answered. If you are stuck due to technical issues during trading time then you are sunk. There is no help in real time. You can not complain to higher authority. Mails of VP / Head of support are not shared.
Even after writing to CEO, Nithin Kamath; the issues are not resolved. They seems to be only interested in increasing the number of clients.
I would advice new investors not get into the trap of discount brokerage just to save few bucks. Better go for reputed brokerages like ICICI, HDFC etc. where you have some support.
