No internet for 14 days!

I’ve had no internet for 14 days - problem confirmed to be on xfinity wiring. Cannot get any response from service technician team - no one has come back since first visit 8/10. Customer service keeps placing “new service ticket”, promises they are routing to technicians. Why are the technicians canceling these tickets? I work for home, should I cancel my service? I’m at the end of my rope here, cannot get any help!
