Complaint

Yes, but this was a major network upgrade, and it took a very long time. An update of this scale should have been performed outside of business hours to avoid disrupting customers. Scheduling it during the workday is unacceptable.

@XfinityPeterH​ "We always do our best to complete work when the majority of users might not be connected" ... is that what you call disconnecting internet service for an unknown length of time starting at 8:30 AM on a business day? When you just had a whole weekend to do the work? 

These excuses are ridiculous, plenty of service companies find ways to do required maintenance without putting their customers out of business during peak hours. Here's an idea: they have these things called "lights". You can bring them to a work site, even up on a pole. Go out, do the repair at night, using these "lights". I know using "lights" is an extraordinarily high-tech solution, but you're a tech company, I'm sure you can find a way to work it out. 

"provide notices of upcoming work online" How exactly is this supposed to compensate me for the work I'm missing? "Oh, I'm losing an indeterminate amount of money and pissing off my boss by not being available during work hours, but at least they told me they were going to do this to me, so that makes it totally ok. Hey, boss, sorry I can't do my job in two days, you're cool paying me to not work right? Comcast gave notice."

I was away for the weekend, I got home Sunday night to "advance notice", dated Friday, that I wouldn't be able to do my job Monday morning. Some "advance notice". Maybe if you're going to put me out of business on Monday, Friday is not exactly "advance notice". People do sometimes go away for the weekend. 

"or our app" ... Oh, yes, your wonderful app, that you require us to use for EVERYTHING, which you changed last year to make sure it wouldn't run on my phone anymore. Sure, I'll just stop using my perfectly functional phone, I'll throw it away, and go spend hundreds of dollars on a new one, because Comcast thinks I should. Tell me, what are those of us who can't run your "app" supposed to do? When I signed up for comcast, it didn't require an "app", and I never would have signed up with comcast if it had. 

And all this while charging me $40/month more than my account is advertised at, 7 months AFTER you told me you'd stop overcharging me. 

You know, it amazes me, the things Comcast is unable to find a way to do:
-You are unable to find away to schedule repairs outside the least convenient time for your customers
-You are unable to find a way to let us get information or change our home network settings without forcing us to do it through the least convenient possible method, an "App" that requires us to spend hundreds of dollars on a smartphone to use it
-You are unable to find a way to stop overcharging us for our accounts, even when we call and talk to you about it and you send an email saying you will stop overcharging
-You are unable to find a way to provide dependable internet service during business hours when I need it
-You are unable to find a way to let us get support from a human being, or at all... all you have is an "assistant" that wastes our time and doesn't help a thing, and these forums, where we can vent into the void and it doesn't accomplish anything.

It seems like your company isn't really good at anything at all except taking our money (more of it than we're supposed to have to pay) and making excuses for why you're unable to give us the advertised service that you're charging us over 50% more than the advertised cost for.
