Consiglio: If you have an appointment with Charter(Spectrum/TimeWarnerCable), don’t answer the phone when we call. 9 times out of 10 we are calling to reschedule your appointment, and company policy states we can’t change it if the customer doesn’t answer the phone

If you can't accommodate lateness or want to reschedule, pick up. Otherwise, never answer and the tech will get there as soon as possible. Answering the phone can only hurt the customer. If we miss your appointment, we would have missed it whether you picked up or not.
