Address: Jaipur, Rajasthan, 302033

I ordered for 50 bandhan bank shares @ 446 but operator manoj purchase 500 shares at that price. And when i ask him how many shares he purchase, he told me that he purchase 50 shares, but actually he purchased 500 shares in my account and sell 450 shares at lie price 437 and cause mr a loss of rs nearly 5000/. Please credit me amount immediately otherwise i will refer matter to sebi. This type of cheating should not be done with good profile client.
