Madaan Cavaliers - Mary Madaan Do not buy a Cavalier from Madaan Cavaliers - Won't provide pedigree or health certificate. Spring, Texas

Early 2010, we purchased a Cavalier from Mary Madaan.  We live in Dallas and drove down to pickup our dog.  Madaan promised the pedigree and health certificate to be mailed to us.  We contacted her for almost a year, at least 20 times.  She lied over and over again, making up one story after another.  She is a scam artist.  She only deals in cash, she hand writes you a reciept and she doesn't take her dogs to the vet.  She administers their shots herself in her living room. 
Our dog has patella problems and who knows what else is wrong with her.  I've reported her to the BBB, AKC, and the Texas commerce department as a fraud.
Hope you read this before you make the mistake we made.
