Angel Broking — Order execution

I had placed an order for coforge call strike price 2500 at premium of 87 .60
I had put a stop loss of 84.50 and the stop loss did not trigger
Also i tried to exit the trade manually but i was unable to
At the end of the day these guys cancelled my trade at a huge loss
I was unable to square of my position
This is a pure mistake at their end
If the balance is cut surely i will embarrass these guys on twitter file a consumer complaint against them and what not
Please keep in mind :)
