why TWO days for planned outage? What do I get for it?

"Our most current information has us doing work in your area on 09/17 and 09/19,"

First message said just 9/17.  new message says 2 days.  THESE ARE BOTH WORK DAYS AND THIS IS TERRIBLE!!!!!!!!!!    

And further reading says this CONTRADICTORY bit:  "We anticipate completing our work within the day."

Which day?   How many hours out?

And as to why you are doing this:   "The goal of the work is to enhance our network to ultimately allow us to deliver multigigabit upload and download speeds. This is just one example of how our next-generation Xfinity network is evolving to get smarter, faster, and more reliable."

... and more costly.       Will my existing speed tier at my existing cost get faster?    Or, will my costs go down for my existing speed?  Either one is acceptable.   Outages for no benefit is not acceptable.
