Best Recirculating Systems in Houston TX

I called early morning to cancel, AS I WAS INSTRUCTED! The plumber, who I am not sure was licensed, showed up anyway. I explained the problem was fixed and I had canceled as I was instructed to do. The guy said well let me take a look. He was there less than 30 minutes and charged me $250. And he did not fix anything. I am outraged and hope this review will serve as a warning!!!!!!
