Horrible! I went with Prism because the price was good and I was looking forward to the DSL option, as well as all the kid HD options. After about a month it all went down hill. I left Cox because I was constantly having to reset my router. The install guy told me I will never have to reset anything with Prism. YAH, right! I'm constantly dealing with freezing, I can't have three tv's on HD channels because one of them will tell me unable to use HD and tells me to shut off a service. Now, I'm experiencing the sound cutting out about every 30 seconds.
Like others I was quoted one price when I signed up and when I received my first bill it was twice as much. I had to call several times for the bonus gift card I was supposed to receive.
The only positive customer service experience I've had was with the Facebook coordinator who actually took the time to help me, once I complained on Facebook. The phone service people don't know how to fix anything. I called with a sound issue one day and all he could suggest was to unplug the box and plug it back in. I ended up fixing it myself.
I can't wait for my contract to be up so I can go back to Cox.
