The Autoridad de Acueductos y Alcantarillados of Puerto Rico is billing me $3,294.54 because they stated we used the water on an unlivable small place we purchased in Puerto Rico. I wrote a couple of letters explaining to them that we live in Naples, Florida and we never resided in Puerto Rico. They don't care and they are still telling me I owe the balance. I am lost and don't know what to do?
