Someone from this office calls almost every day, sometime twice a day (woman in the morning, man in the afternoon), asking for our CEO by name - who won't take their calls until he knows who they are and what they want.  I offer to take a message; they always say they'll call late...which they do.  I've asked if this is a solicitation.  Their reply, "This is just a courtesy call."  Well, then tell me who you are and what you want.

who  is this quit calling me

receives calls regularly from this number, no talk on the other end
