Helderberg Exotic Cats review: The lady sold me sick kittens

I have purchased two Bengal kittens from Helderberg Exotic Cats. These kittens looked nice and so lovely, but when I brought them home, I noticed that they were sick. I went to vet next day and the staff said that these kittens had some rear disease and it was impossible to cure. I called to the breeder and said her everything what I thought, but this lady simply hung up on me.
