Calling our office phone; I don't answer calls when I don't recognize the number; We are, for some reason, beginning to receive these calls at work from several different numbers. And I don't answer. I've told my boss not to answer when the name/number on the caller ID is unfamiliar because if it is a legitimate call, the caller will leave a voice mail message.
I have received calls from this number several times and each time I have pressed 2 to hopefully end them. However they are still coming. This time I did share this number with the federal authorities. Hopefully they can stop these people from calling other who have no interest in what they are doing.
