You are correct. Saw a news program on "pressing 2" to be removed. It only removes your number from the one that just called but in term gives them the okay to sell your number to these other scammers. You are NEVER truely removed from the list. Signing up on the do not call list is a waste of time. I just set my call block to not ring outside of my contacts.

Comes up SBC Internet services. Scammer/harasser just wasting their time, not mine.
