I received a call from this number and when I tried to return the call I was told that no one at this association could return my call, but to leave my name and number and my call would be returned - no company name, nothing, just 'this association'.  I would like to know who this is calling.  They have called twice in one day.

multiple calls. No voice. Extremely annoying

Yeah, for some reason I'm getting repeated calls from this number also. Have yet to answer. I don't answer from numbers I don't recognize and/or where it says Unavailable or Restricted. Just sayin. But how can I get this stopped, or can I even. I don't have the super dooper phone with all the bells and whistles so I don't have a Blocking App or anything. :/ Very annoying indeed!

Asked for me by my first name. When I asked who was calling, replied that it was a courtesy call for Firstname. Again I asked who was calling, and the male voice on the other end angrily snapped "I guess Firstname isn't there!" and hung up. Interesting interpretation of "courtesy."
