This number has been calling without leaving a message. On call back there is a recording which states "It is important that we speak with you." It is National Enterprise Systems (NES). I believe they are a debt collection agency.
This is happening daily: "Is this R . . . . . Please press one now. To place this call on hold to allow time for this person to come to the phone please press two. If this is the correct household but the person is not available please press three. If this person does not live at this address please press four." What a PiTA!
