I knew about karvy stock broking from wayto sms. I just called them for interest. After that they call me back to back for 10 to 11 time. I opened acount, because they said free of caust I can trade from their app. But there are many hidden charges which they did not say me. First time in my life I trading. So I dont have knowledge. But their customer executive never help me. All time disturbing me for POA submission. When I ask them what is the charges? They disconnected call. Broking charges very high. Their service also bad.
