I would just keep looking. They cannot find you if you aren't looking for their way of contacting you.
It seems like everything anymore has a horrendous SCAM factor. I think you are learning to 'read' the 'language' of the scam. If the communication sounds 'translated' to English...likely a scam. If they are promising a whole bunch for next to nothing...likely a scam. I know some highly reputable breeders will sometimes arrange transportation or delivery of a puppy...but when the whole package is less than airfare, I'd be more than mighty suspicious.
There is a Yorkie baby waiting for you to help him/her find you.
