It's such fun to come home from a hectic day at work and have the phone ringing from creditors with an "extremely urgent" need to speak with me. Yes, and it's extremely urgent that I collect about $35,000 from clients who are in arrears. I'll get to it as soon as I have time. In the meantime, as Billie Holiday might sing, "Do Nothing Til You Hear From Me. And you never will."
Fire the person who is making these stupid calls, and you'll save about what I owe you.
