Got this call on my cell phone on October 26th at 4:49 p.m., Pacific time too, but couldn't make out who they were when she introduced herself.  She asked if this was (my name) and I said "no".  The automated message then asked if (my name) is available.  I again said "no".  The message then asked if I was willing to take a message for (my name).  Again I said no...then the caller hung up after saying thank you.
