My xfinity cable was cut during a home renovation and its just laying in the yard, how do I get it reconnected?

All the utilities to my house were re-routed during a significant renovation and the xfinity troubleshooting chat-bot does not seem to understand that as a potential problem someone can have.  I have scheduled a service call through that bot but they think their just coming to troubleshoot a modem issue.  I need them to understand this is more like a new home installation and not just a simple service call.  How do I get in touch with a human at xfinity to discuss this?
