Their service seems to be good for me, few interruptions, good internet speed.
Price is ridiculous. For basic cable in my area (no digital, no box) price is hitting closing to $60/month, internet is about $42. Most they would give me off my bill is $15 so instead of $100/month, it's $85. When that expires next month I'll call again and hopefully they will try to retain me so I don't have to hassle with switching service.
I also hate their non-stop bombardment of advertisements. Commercial after commercial on TV, mailings every week, it just doesn't end.
If you move or cancel, good luck with that, especially if you have auto pay set up for your account.
