You're mistaken. The passengers tell the flight attendants, the flight attendants tell the captain, and the captain ACARS his or her dispatcher.
Not uncommon at all.
You are right in assuming somebody at the company already knows. The pilots don't know or care about that. From their perspective, taking 30 seconds to pass that information to the SOC can't hurt, and then the flight attendant can tell the passenger that the company was "notified".
