Proactive maintenance leads to outage, no tech for 3 days?

Comcast messaged me today that they have detected a problem and are working on it (my home Internet was working fine). Internet went down for 4-5 hours. Got message that it is up and running; no Internet. Xfinity Assistant said to reboot modem., did that - no Internet. Then XA said there is a problem with the signal to reboot again, did that - no Internet. Received tech scheduling text - first available is 3 days out. Other neighbors having same issue so this is not single home issue.
