People, in general, seem to HATE Cox. But I was a customer for years and thought they were pretty great. I mean, sure the cost of service is high and there were occasional technical difficulties, but they are no worse than AT&T or Time Warner. I mean, they're way better than one of those.
I'm with AT&T U-verse right now, but would gladly go back with Cox if things don't work out with AT&T.
I think a lot of the complaints against Cox can be found on the Yelp pages of every other service provider in San Diego. Cheap, consistent, and simple high-speed data services are not really an option here. In San Diego, California, or the whole of America.
