Called my office TWICE in the last hour. The 2nd time they called I picked up the receiver and put it on the desk so they could hear the background noise...I figured it would annoy them ! Next time I'll hit the receiver against the desk so their ears hurt :)
You can simply ask them to take your name off. I share an office with them in the state's capitol so I feel weird doing this but I just don't have any money to give.... they are a good group.
