Avoid tele-marketing call

I can recognize a telemarketing call within 10 seconds of receiving the call. My immedate answer is "I am not interested" and I put down the phone immediately.  The telemarketer recognize a rejection and do not call back. If the telemarketer calls back (which never happens), I will lodge a complaint for harassment.

If someone wishes to market any product to me, they can send an e-mail to me. I can decide whether to read it or to delete it.
