This number also called my landline and was blocked after the first ring by my free blocking service. This time they called when I was home so I know it was blocked. Since it is blocked, I called it back and the general recording was  that no one was available to answer the call and that they would call back in a day and to press one if you'd like to be removed from their list . I chose not to press one, they won't get through the next time if they do call. I have had other numbers that also indicate they will call back and somehow they never do.
