I didn't answer and they left no message, however I am expecting a visit from a Charter cable guy tomorrow, so I imagine the above comments are true. Confirmation of appointment from an automated system.

This number called me but left no message.

800-374-1214 it for Charter Communications - confirmting an appointment for TV/Phone/Internet cable connection - mine was based on an appointment I setup to have them come in and setup my cable.

Recording about confirming an appointment but no date or time....
