Calls our business number frequently asking for Kim.  When I inform her that no Kim works here, she asks for the 'expenditures' dept.  Says she is calling from a charity, but always mumbles the name of her company or hesitates when I ask who they are or what they do.  When I offer to take her information and have someone call her back, she always tells me she will call  back later.  Now I just don't answer the calls.

Received a call Sunday at 7:00 p.m.  I didn't answer - no message left

Calls frequently.  Just called at 0830 in the morning.  I don't answer and no message left.
