18 calls from this number over the last 3 days!! Obviously a scam. I never answer calls from numbers I don't know and they NEVER leave a message. This scammer is very, very persistent though... hopefully they will get the message soon to stop wasting their and my time!
I have caller id so I know if the call is from someone calling that I want to talk to. I just don't answer when I see it is an unfamiliar number. Lately though, when I get these calls, I just pick up the phone and lay it down on my desk. I like to think that whoever is calling gets very angry because it is using up their time, which to me, is much less important than my time. If the call is important the caller may leave a message on my machine. If the call is not important enough to leave a message, well, I never really missed anything.
