Trouble getting servo to work

Again, note that the 500mA spec is for no-load operation. This is just to produce enough torque to overcome the internal friction. If there is a load resisting the servo's attempted travel, the current use for each servo could easily be several amps.

I dont think we tried plugging into a different PWM port. It returns to zero even when disabled.

Is the PWM wire plugged in with the correct orientation? When the roboRio is disabled, the servo should be getting no PWM signal to go to any position including zero.
