She looks Yorkie now but since you didn't go to a reputable breeder i.e. papers were included, parents lineage confirmed etc., you will have no idea until she is older. Unfortunately, you have put yourself in the position that you will have to take the breeders word for it even if she misled you.
She's cute though so I hope you will love her no matter what!
Wanted to add that I especially like this pic:
