We get like 30 calls a day from an unidentified 1 800 number. Our bills are all paid up, so I don't know what they want. And I don't really give a crap.
If your business can't identify itself via Caller Id, then screw off and quit calling. 'Cause you ain't ever talking to anyone in this house.
Edit - I tried a couple of online reverse look up tools, but I am not willing to pay $12-$15 to find out who is calling me all freakin' day. Anyone want to give it a crack?
