We are continually getting calls from this number. They never speak, never leave a message, and do not respond to our request to put us on their Do Not Call List.

We used to get calls from Test Code NY and they have changed to Plant Test NY.  Same MO I.e. no answer and no response to us.  When called back we are informed that the number is not in service.  Now I just let it ring until the answering machine takes over.  Anyone know anything about this?
