Another new number calling today. First was our old friend from card services, now this one. Seems they only call once anymore, than just use another new number later. Unless they call more than once, I don't even bother to block them anymore, as they just use a new number!
When they did not leave a message the first time, I blocked them. They still continue to call and since they are blocked it only rings once and they show up on caller ID.
