Always take a Screen shot of a website before you tell someone their websites states... The reason for this is because they can simply go change it. And I would argue it with them, file a complaint with the housing authority in your area if they refuse to make it right. Make it public, there maybe many more people in your HOA that have been overcharged. But do not spend to much effort on it, as there are more important things to do in this short life we have.
