Xfinity Service under constant outage. Can't rely on the service and am not allowed to talk to Agent because I'm in outage! ???

I have been under an outage for over 1 month and my service is so unreliable I can no longer run by business from it.  I cannot contact support because I am always under and outage.  No one has contacted me.  Worst yet my phone is disconnected saying "Agents can not help you while you are in an outage!".
