How to deal with a telemarketer
For many of us unsolicited marketing calls is a big nuisance. There is really not much you can do to prevent these calls. However as the following video shows sometimes it is the telemarketer who is at the receiving end. Highly recommended for anyone planning to join call centre work! It is the funniest prank call I have heard 
Tom Mabe is telemarketer’s nightmare

Actually there is a lot to do to prevent telemarketers by calling.
1. Submit your # to the do not call list. http://www.donotcall.gov
2. If you did not submit it yet and receive a call interrupt the caller and tell them “place me on your do not call list”.
By law they must stop the conversation immediately and take down your number so they can add it to their do not call list. After that the are not allowed to call you ever again. If they do, you report them to the FTC where they get steep fines. Shutting them up is actually very simple, since they don’t want to brake any laws.
I should know, I used to be a telemarketer or telephone sales rep.
