If you think that a crime has been committed (which you obviously do as you are calling the transaction you made with the unnamed breeder fraudulent) then report it to the relevant authorities.
There's nothing that anyone on the forum can do to help - except if you have reason to believe that someone else on here has regular contact with the breeder, in that case you could ask that person if they'd be willing to contact the breeder on your behalf, it may make no difference but if there's been a simple misunderstanding it could clear things up. Of course, unless you read a lot of background posts you don't really know who has regular contact with who, but it's about all you can do on the forum.

I don't know what you hope to gain by posting vague descriptions of your experience. It doesn't serve as information that could be useful to anyone else buying snakes. If the breeders has really defrauded you then privately naming them to a moderator could enable them to prevent the breeder advertising on here again.
