Unhappy with length of maintenance in neighborhood.

I've tried other methods to raise this with Xfinity but none seem to be successful. I work at home 100% of the time and am reliant on my internet service. Last Friday I received a notice that upgrade work would be needed in my neighborhood Monday (9/11) and that it was "expected to be done within the day." Well Monday it rained and they rescheduled to Tuesday. Fine and understandable. Well, Tuesday afternoon rolls around and I get a message that they didn't finish that day after all.  Said they would be back Wednesday.  Wednesday afternoon I get the same message, saying they would be back Thursday. What was supposed to be a day's worth of work has now turned into four days, and for the last four days I've been told repeatedly that it would be done in one day. This has disrupted my whole week as I have had to find alternate places to work. Needless to say I am not happy about this and would like someone to look into what the hold up is. I would have been happy to email this to customer service privately, but that apparently is not an option anymore, so here it is.
