I received a call from this number. It was a genuine call from Charter (now Spectrum) from a automated system to confirm an appointment for a service technician to visit my home. It is not a scam.
Not a scam. It actually is Charter Spectrum. If they are calling you and you haven't scheduled an appt, it is an error and whoever is waiting for the service tech will think Charter dropped the ball and isn't coming to fix their issue. The tech could actually be parked down the street, waiting to confirm the address and that the customer will be there to let him in.
