Faxhalt is what came up in the ID, but it was far from that type of service.
They had an old book for and tried to contact a retired Realtor.

Global Collection Network, Collection Agency claims you can be removed from their fax list if
you dial 877-213-4099 but I don't believe it, since the number they were trying to reach was over ten years old.

http://gcncompany.com/  is their web address
This what shows up there:
Phone: (866) 213-4099    Fax : (866) 213-7688
Email: [email protected]

They do not provide a land office address.
But I am not going to do anything to encourage further contact.
