Request for Service, Tier 2 agent/supervisor or higher

We had an internet outage in the area earlier this week on Monday June 11, received a text that service was restored but the internet still wasn't working. Replaced the modem with a new one from Comcast. Have tried all the troubleshooting methods multiple times with no resolution. Can't get an appointment for over a week. Is there a way I can't get a technician out there sooner?
