I called their toll free number and the receptionist accepted my requets to be taken off the call list. She said it takes about 24 hours to be removed.

You know all you have to do is say remove me from the list right?

At first I avoided the call thinking it was just the usual telemarketer or someone calling to do a survey. Turns out they are a huge help for me and my organization. They are an I.T Research and Advisory firm.

Hey folks...I work at this company. I hate the fact people associate our number with something annoying. Let's try this for an approach. If you're getting calls from us, and want them to stop - call me. I'm a Director with Info-Tech and will work to fix your problem. I can remove you from the list immediately or I can let you talk to someone about who we are (your choice...I won't ask you to do one before the other). I encourage someone to try this out and post some feedback here for others to follow suit.

Are you stupid? Read the comments. People ask to be removed over and over and they still call back.

I am ignoring them, but they keep ringing! How on earth did they get my number!
