At the end of the day, does it really matter what your pup is crossed with the pure and simple fact is that this pup has been sold as something it is not, the 'breeder' has lied, and given a faulse pedigree. Though as already quoted nothing is official unless it comes from the Kennel Club.
Personally I would be writing to this owner and explain that you will be involving the police, trading standards, the association that infact wrote out the faulse pedigree, (that it is) and personally you should do these things anyway to save them conning other people, unless a full refund is given back immediately.
Not only is the pup a lie, but stress the emotional pain that come into this too. You also have a dog that may not turn out to be Cocker like, may have to be leaded on walks (as many Beagles have the call of the wild so strong they can not be off lead) health issues may also come into play here, were the parents health tested etc? (I doubt it) quite frankly you don't know what you are to end up with.
Why oh why with all the warnings did you not buy a KC registered pup with all health tested parents documents to go with it??
You have everything on your side this person is a con artist and a liar.
I would be hell bent on justice and no way should you allow yourself to be strung along any longer.
Your pup is gorgeous nonetheless and I know your heart strings are most likely pulling to keep her and you probably will, it would be hard to give her up now, but if you wanted a Cocker in the first place it may be worth considering.
