I am really sorry you ended up with these sick snakes. As was said before quartine these 3 to make sure you don't spread anything to your other snakes.

I would also definitly post up this guys name and email all over BP.net's feedback forum and the BOI on faunaclassifieds to make sure this guy can't do this to anyone else.

This happened to me once with 1 snake. Now I just buy from 2 local breeders who I trust.
