Cox Communications constantly misrepresents product & cost and inept billing & customer service San Diego, California

When we signed up for Cox Communications for Internet, Cable TV and Phone and quoted an amount; we believed them.  Our bill was double that amount.  When we went to cancel our subscription with Cox Communications, we were told if we subscribe to a "promotion" to get Starz, HBO, Cinemax our "bundle rate" will be lower than what we initially agreed upon.  Told its good for 6-months, at the end of one month, our Cox billed doubled.  When we called to cancel our service, we were told there is a penalty to cancel before the "6-month agreement" that was for 3-months.  Cox can change the agreement, but the consumer being taken advantage of, has no rights to cancel.  Our Cox monthly statements from that point, doubled, then tripled.  Each time, Cox promised our monthly bill will adjust to a lesser amount (quoted to us) and Cox statements escalated to more then triple what we ever agreed upon.  We were never late on a payment - even though it wasn't what we agreed upon. 
Cox is notorious for this.  The Public Utilities Commission is to regulate Cox Communications and we've sent several complaints to the PUC, however, the PUC hasn't bothered to intervene. 
Consumer's Be Ware -  Cox is not ethical and whatever agreement you may think you have with them, they alter without consideration of what is ethical and without consideration of what is agreed upon.
