Jet Airways — about the staff

I reached at the airport at 11:40am my flight was at 12:40pm.
The staff of jet airways made me wander from counter to counter and then it was 11:50am and then the one staff whom i asked for the boarding pass said that the seats were full and she cannot provide me with a boarding pass.
Why do you take reservations when you dont have a seat?
And that staff name was sonia.
She didnt even talk properly.
Teach her to talk to customer with some decency.
I want my refund of 2089 because i was at time and your staff is not proper.
