Caller: spammer robot

called by automated voice telling me my TOLL package was undeliverable and this was the last attempt.blah blah blah de blah!...then voice went into chinese. FYI nothing due for delivery......SOooooooo ?? My phone identified it as SPAM..but I answered anyways for some light entertainment..hope it cost them $$$ as it came from landline & across the other side of the country. Yet another added to blocked list
