Intermittent Outages over Multiple Days - Need Explanation and More Than a Refund

My Xfinity home internet has experienced outages every day since August 13. It was out most of the day on August 13 due to "upgrades in my area" and has been intermittently out for an hour or so at a time, multiple times a day, every day since. This morning it says it was because of a "power outage."

I'd like an actual explanation of the reasons for these outages. I'd also like more than the $10 refund I've been offered by the online system - my spouse is a work from home freelancer and has not been able to work reliably for the past several days because of this problem, causing a significant inability to earn money. $10 does not cover the impact of this outage.

I've been an Xfinity customer since I moved into the house more than a year ago and haven't had issues until now, and it's making me consider a different provider.
