Has anyone heard of the st. helena pet shipping company?

theyre supposed to be shipping my puppy from st. helena to me here in tennesee, and after i paid the transportation fee, they told me the insurance onthe dog had expired. And to renew it would b $220 .. but i begged them and one of the guys help me pay $100.. i jus want to know if this company actually exists or is it all a scam.
