We have recieved calls from this fax line 720-606-7065 also - several times a day.. I called 720-606-7060 and it answers " you have reached NEFCOWA if you are recieving unwanted fax calls from us and wish to be taken off our list and add to our do not call list please enter the number we are calling"
So I entered out office number and hopefully it stops...
I recommend everyone do the same.
