I was given AKC paperwork to a dead dog?? What should I do?

I purchased a Boxer that was supposed to be AKC. When I got her home and the AKC paperwork I was given home, I looked at the paperwork and noticed that parents names didn't match who she told me they was. I called her and she said that the dog I bought was only CKC registered. The papers she gave me was AKC paperwork to a dog that looked just like mine from a totally differnt bloodlines that died from PARVO! She said she thought the AKC paperwork would help me so I could AKC register her and breed her. Should I turn her into AKC and if I do what will they do??
