She went ahead and paid the additional "fee"; now she was out $2,920! Then they said they needed another $4,500 for something else. This scam keeps keeps going as long as the buyer keeps sending money.
Well, Kellie didn't give them the $4,500... finally! Authorities said that the operations were most likely based in Nigeria, where crooks have made it a big business stealing people's money via the web.
Let's make this clear... there are no puppies! Any certificates are bogus, and any demands for more money are a SCAM! And they will do this with anything, even "selling people". Don't fall for it! They operate on this principle: If people are gullible enough to give them money, it's their own fault. The scammers feel no shame!
