Cedar Ridge Kennels AKA Paradise Pups Cindy Maxted Jensen review: False advertising; unethical behavior

I purchased a female golden retriever for $600 from her on 7/30/2016 with the understanding that she would mail the AKC papers to me because she hadn't received them. Since then, I've contacted her numerous times (8/17, 8/21, 8/22, 9/4, 9/7, 9/9, 9/13, 9/15, and 9/17). My text messages are super nice..."Hi, just checking on the papers." She replied to me one time, on 8/23, to let me know she was out of state. That's the last I heard from her. On 9/15, I stressed my concern and begged her to touch base with me. On 9/17 I point blank asked if she ripped me off. Still no response. It's been 4 weeks since I've heard from her. I'm concerned that my puppy isn't purebred (not that I love her any less for it, but) I hate that I was potentially lied to and taken advantage of. I just want what I paid for, what was advertised, and what we agreed to.
