I am a total hack and I call you to verify your contact information which I then sell to the highest bidder, well any bidder actually. The 'bidders', vendors and such, then also call you hocking their wares. All these calls then take a lot of your time leaving you with that 'what the heck did I do all day' feeling. As this is the time of year to air wrongdoing and move forward with a clean slate, I'd like to extend my sincerest apologies for calling you this year. Cheers to the New Year! Talk to you soon! Anne Campbell (ok just kidding, this isn't really Anne Campbell)

Same thing, happened to me today. Looked her name and number up and now that I read this dialogue I'm even more confident about not responding. If I reach her live I will give her this feedback.

I get the same voicemail message on my business phone once per week. Caller ID = PRIVATE CALLER"
"Hi This is Ann Campbell calling, would you please give me a call back at xxx-xxx-xxxx" Never does she identify what the purpose of her call is for. Very unprofessional. I will not call back

This number calls me several times a day!  I have gotten a couple of voice mail messages that it is from an Anne Campbell -- no company name -- no purpose of the call.  I ignore it every time I see the number on my phone.  Very annoying.  People like this are ignorant if they think that business people will answer when they don't leave a legitimate business reason for their phone call.  

Same Message

I also Just got the same mssg-exactly as described earlier.  I have no intention of returning the call

Just got the same message, Anne Campbell, no company name, left this number.  I didn't call back.

Found out that this call is from Arizona.  The message left on our HR voice mail:  Please call Ann Campbell / No company name.
