Internet went down 6/29. The soonest technician available would be 7/7. After the technician didn’t show, I called Xfinity. They said my appointment got canceled on their end. The next appointment 7/21.

I had 5-G internet it was fine, good signal and reliable. But when I need customer service, I spent 6 days averaging 1.5 hours a day trying to get help. That was 9 HOURS!! A good part of it 9 hours was stuck in their automated system. I moved. My new address was wrong. The system could cope with that. It only holds two addresses at a time. Even when I got a live person they would tell me it was fix. But I check the next day and it was not fixed; a week, two weeks later not fixed. Which mean no service at my new location. I finally gave up and when with Ziply Fiber. 1 phone call and service 2 days later. Ziply has a better picture quality and it is $20.00 cheap each month. My recommendation if there is Ziply Fiber in your area, go with them.

Service was internet only, automatic bill pay, paper billing. I would randomly receive phone calls at work regarding my bill. I would question the call as I had automatic bill pay. The representative would look into my account and state, "Sorry for the call, everything is good." This happened about three or four times. One day I just randomly opened up the paper bill. Those Cheats were charging me a late fee, disconnect fee, and a reconnect fee all in the same day my bill was due. My monthly bank statements confirmed that they were withdrawing the funds and that the funds were available. They had been doing that for months. I was livid. I'm still livid. Watch your bills people corporations do and will steal.

Company Officials telling lies about their internet causing undue stress and wasted valuable time. Officials stressed my internet would not longer function without using their cable modem. This was not true. Officials also stated this would be no cost in using their cable modem. This was not true as well.

This company has the worst customer service EVER! They don’t care about your issues. There employees at the store lie, the on phone people speak English but can’t understand it. I’ll pay more any day to not deal with this mess.

My name is Roderick and I live in a an assisted living house, I’m paying rent and cable/internet and not receiving any internet service, I had the manager call Comcast repeatedly to complain, and Comcast sent some suspect tech. He had no boots on, work uniform and needless to say the problem didn’t get fixed. The next time they sent an actual tech and she replaced the wires outside, replaced the wires inside and told us this would fix our internet problem, needless to say the problem wasn’t fixed. Now I’m starting to feel like a robbery victim, cause Comcast is charging us and not giving us any internet! I really wish Comcast would fix this problem before we switch back to Verizon. The owner of this business switched from Verizon to Comcast, probably because of the price. But there is nothing higher than no internet service for any price. Verizon was costly but you get what you pay for, and right now we are getting nothing!

Used Comcast Business Internet with 5 Static IPs and a Phone Line in 2008 in Minneapolis, MN. In 2020, they failed to move my service to Wesley Chapel, FL but charged me for 2 years. They talked to me in 2020, made me sign the change of address forms and even arranged a site survey. They never told me that service was unavailable at their location. When I got to Florida, I realized that my line was not up yet. When I contacted them, they said that I had to continue paying for the next two years because it was my fault that they do not provide service at my location. Unbelievably unethical - charging me about $270.00 every month for 24 months when I was specifically told by their tech that my service would be moved and further charging me $124.90 for installation charges.

The location in which I have service has old/outdated connections outside and Comcast will not update the area. I hate calling about it as they continue to tie me up with higher bills and longer contracts but same poor service.

We have had 3 outages with this company in less than two weeks. This has occurred during the daytime, evening prime time and 1 other time. When we call we are told that this is regular maintenance, which is unacceptable. They do not provide any live customer service, and these outages can be up to 12 hours long. This is the only service provider in this area.

We are limited with internet providers in our area. Comcast provides services to our location. 3 phone lines. Internet. We've purchased/contracted these services for $180-$230/month for over 2 years. This last January the bill kept jumping. I'd call for service, they'd give me a credit. January. Credit. February. Credit. March, again followed up by a credit. I had to call them each time. Then the April bill jumps to $630/month. I call. This time, no credit. No recourse? That's not okay.

With roots in cable, Comcast is the largest business VoIP service provider in the United States. It provides a variety of data and communications services to businesses of all sizes.
Fixed-mobile convergence: Calls taken on a desk phone can be transferred in mid-call to mobiles. Calls can also automatically be forwarded to smart phones running as extensions to Comcast's virtual PBX. Caller ID shows as your business number, in either case.
Voice Mobility pricing: Comcast's Voice Mobility service is $29.99 per month for one line and requires a Comcast Internet plan as well. Voicemail boxes are an additional $5 per month.
VoiceEdge: Comcast's hosted PBX solution, VoiceEdge, starts at $34.95 per line for up to five lines and drops to $24.95 per line for 25 or more lines.
Network quality: Comcast undertakes a comprehensive network assessment before beginning voice service. Network quality is continually monitored, and SLAs are offered on service and installed devices such as routers and phone sets.
Sign on additional SIP trunks: Comcast can assign additional SIP trunks on an as-needed basis for periods of high call volume.
