Cox stopped my Fox News 2 Go Service?

I have been watching Fox News Go live on my cell phone for a while. About 3 weeks ago I was no longer able to access Fox Live news. I started getting "Authorization Denied" error messages. I contacted my cell comp and the Fox news people. They all said it was on Cox's end. It seems to be a recurring thing with Cox. They seem to be blocking access to what ever they want.
