That is a Presta-valve. To fill a Presta tube you first need to unscrew (counter-clockwise) the little brass nut on the top of it - at the end of the valve. It does not fully unscrew - just maybe 5mm or so. If the tube has air in it already, just press down on the end of the valve so it blows out some air. This ensures the valve is open and clear. No air? Don't worry. Now press the pump chuck (the part the air goes through) firmly down on the valve. Then flip the lever to close the chuck around the valve. Pump! Pump! Pump!

If it still doesn't work - go yell at the salesman.
