For the record, while there are occassional issues; the general overall performance is better than one might believe from the complaints. If everything is working well, there is no need to take the time to log-in and write something. Given the technical nature of the service, the multitude of things that can go wrong, and demand placed on the system, they're doing pretty well.
I've been with Cox since 2006 and on a scale of 1-10, they would be a 9 in my book. Granted, when I have issues, it would be nice to have a direct way to get it fixed and fixed quickly, but overall, they have been responsive and helpful when you get to the right person.
