Small fridge

Question

My 4 month old fridge westinghouse ( top freezer compact) sorry don't know the model was leaking water into from the freezer into the fridge though where you regulate the temp. On investigation i noted that the temp had been turned down (suspect my grand daughter) i turned it back up to medium now the freezer is making snow around the door and the fridge is quite warm. help please do i need a call out ?
