Pup Paws Dog Breeders Hasn't provided akc registration papers Wasola Missouri

My husband drove down with our kids to purchase a toy yorkie from Dianna and we had to meet her at McDonalds which we thought was weird,  so she arrived and we paid with a check and she said she normally doesn't take checks, but since we drove almost 4 hours she would but wouldn't send the akc registration papers until the check cleared. Well the check cleared a few days later and this was the last week of February and it is now May and we still haven't received the paperwork.  I have emailed and called and she won't respond.  Our dog did have bloody stools and we had him checked out received meds and luckily he is ok. This is a horrible company and now I'm concerned about the other puppies left in her care and what other lies has she told. I don't want anyone else to get scammed my this woman or company
