Hades also doesn't talk to Hazel because it would be admitting that she came back from the dead, and then he would have to bring her back. As for Percy not getting any communications from Poseidon, as a member of the Big Three, and one who has (as far as Zeus/Jupiter is concerned) already tried to rebell against Zeus, most likely has been under a tight watch. Zeus didn't talk at all with Jason, and the only real asisstance was a giant lightning bolt, not talking like the other gods to their kids. None of the big three have talked to their representatives in the Seven (Jason, Percy, or Hazel)
