Jet Airways — false information from the kisk assistance

I'm jean eddy amajuste, i should fly to pap with my family (Wife and son): taciana charles and flavio nemamiah amajuste, this morning at 9h10 am. My boarding pass wrote f10, at the kiosk the agent repeated go to f10. I missed my flight cause the gate was wrong, the board was at f1 instead. I'm travelling with my 20 months son, i'm at the airport till the next flight at 3pm and don't have money to take care my son. I kindly request a compensation for that harm.

Regards,
Jean eddy amajuste and taciana charles
