As a flight attendant and a purser I can tell you that you did everything correctly.
Here is my advice to everyone. If you can't get the flight attendant to remedy the situation, hang out in the galley. If they tell you to sit down, tell them you fear for your safety. That should set the wheels into motion!
Note: This works in ALL situations
