Xfinity maintenance on our street caused our outage, still no service

Yesterday there was an Xfinity maintenance apparently to fix something done on our street, we saw them right outside our house. After they were done, we lost our service both Internet and TV. We reported it through their text messaging but no success. Called cust service, went thru the entire usual process of with cust service still nothing. The earliest they can schedule a technician is tomorrow. We did not have any service issue until the Xfinity crew fixed something on the street and now we have an actual outage and couldn't find anywhere to report it to except customer service. The Xfinity maintenance caused our outage yet we have to wait two days for someone to have a look ! This is frustrating. And it's a weekday!  Cust service says it's the best they can do.  Can we get someone from Xfinity have a look without waiting for another 30 hrs? This was caused by their crew tinkering supposedly doing maintenance to enhance customer experience, as what their automated message said and here we are 24 hrs later and still no TV and Internet.
