I've asked a Comcast employee to help you. You should expect a reply in this thread.
FYI: They owe you a $20 credit for each missed appointment.
Hello mickov, I show that we have a tech scheduled to come out tomorrow to wire your home for services. After the wires have been installed another tech will come out and activate your services.
Hello mickov, I wanted to touch base with you to see how everything went with our technician. Did we get your issue taken care of?
