Cancellation

Mr. C - "No one told me I had to tell you when I cancelled"

Me - "It is standard practice to tell a company when you no longer want their services."

Mr. C - "No, it isn't. Don't give me that. That's ridiculous."

Me - "Sir, there is no way for us to know that you no longer want service unless you tell us."

Mr. C - "I need to speak to your manager about this."
