Lack of Customer Focus for planned service outage

During a conference call today that I was hosting, and utilizing internet WebEx hosting, I suddenly lost phone and internet services.  No warning, just a sudden failed line and service.  I tried to call back in, but the phone was dead.  I looked outside and saw an Xfinity Service Van.  I walked out and asked what had happened.  He said it was a planned outage that would only take 30-mins or so.   I asked if it had been communicated to area customers and he didn't think so due to the proximity of the area impacted.  My question to him was "Why not?".  If I had known a short outage was planned, I could have rescheduled my meeting.  This is very poor customer service!
