To provide feedback for a specific number, simply locate the call in your Recents list within RoboKiller and select the drop-down arrow on the right side. This will reveal the Call Details screen which provides you with information regarding the call. From here, you can leave 'Feedback' about the number.

Leaving feedback will allow you to report this number directly to us, and add it to your block list so that you aren't bothered by that same number in the future.
