Mr. Number is an app you can download onto your phone and when a telemarketer calls, you can add it to Mr. Number and block it, hang up on it, or send it to voice mail. I use this app with EVERY telemarketer and have had very little calls since then. I just received a call from this number and added it to Mr. number, I won't be hearing from them again. It's an awesome app.

Here is the online complaint site for the FCC. They do actually follow up.

If I don't recognize the number I don't answer. If it is important they can leave a voicemail. If they don't leave a voicemail, oh well.
