When a telemarketer calls I try to use up as much of their time as possible, then when I have thought of just about every question possible to ask the telemarketer, I tell them what VP CHeney told Senator Pat Leahy recently -
"F*** off and take my name and number off your list. On one occasion I told the caller that I needed their billing address because they had called my private line and I was forced to send them a bill for $250.00 for their call. After going through the original caller and two supervisors they said they would take me off the list. There are plenty of games you can play with them and have some fun at their expense.
