Manager number?

Does anyone know how to actually speak to a human manager? We’ve just started with xfinity and have only had internet for 7 of the 14 days we’ve had a contract. The first cable that was installed was chewed up by a bunny, the first appointment they had to fix it the tech never showed and they got us another appointment 3 days later after a 45 minute call. He did a great job and even made sure all the cable was propped up by trees and shrubs to prevent the bunny damage. 
unfortunately, the following day the bury crew showed up and broke the cable. They tried to fix it but were unsuccessful. I spent 40 minutes on the phone to get another appointment for 4 days out, I said that wasn’t acceptable since their team broke our internet connection less than 24 hours after fixing it so they said they’d have someone here this morning. That appointment was also canceled. I’m just at my wits end here paying for a service we haven’t been able to use and it takes over 40 minutes on a call to even schedule an appointment and then it’s all 3-5 days out. Not having home internet is extremely disruptive and I need someone who can actually help me get this sorted out asap.
