Narrative:
After a normal takeoff; tower switched us to departure. After checking in with the controller; he told us to climb to 8000 ft and to turn to a heading of 100 degrees. I acknowledged with a full readback and the first officer acknowledged inside the cockpit too. When passing 6000 ft the controller inquired about the altitude crossing at that time. We responded 6000 climbing to 8000. He paused and answered; 'you were cleared to 4000 ft but no problem; climb to 8000'. In this specific scenario; both of us heard clearly and acknowledged the altitude and heading command without any kind of doubt or hesitation. We believe the controller has to pay more attention to either the command he gave us or the readback from the flying crew to avoid this type of confusion.
