As I mentioned a few times, this exact same thing happened to me many years ago, here in Texas.  Complained but only got vague answers back.  I really think that if you are going to send people to jail for voting improperly (even by accident) then removing people from voting like this, with no notice, needs to be taken more seriously People need to go to jail.  This is a rampant systematic crime in many parts of the US and nobody seems interested in addressing it.
