The issue is how to get in contact with someone intelligent who can make decisions. Clearly they would be in violation of the law if they took your money for one thing and gave you something else. And there would be no reason for them to not want to fix it.
I might send a letter saying something like this. That way, you can overlap parallel avenues of communication.
You are in violation of the law. But I am hoping this will be resolved before you get this letter.
