Charter Communications Horrible billing errors, will not respond to settle dispute Nationwide

We started our cable service with Charter communications on February 16, 2007. Since then we have had our service shut off 4 times and atleast $300 worth of billing errors, if not more.

We set up service for a package charter had at the time, it was for the Big movie package (which included one movie tier, we chose Showtime) , it also included their 3meg internet and phone services for 99.99/mth. 2 months into the service I suddenly received a bill for $280. It was our second bill and the jump in cost surprised me.
Every time I called I was simply told, "We bill a month in advance." which had nothing to do with why I was calling. I found out after multiple phone calls that they had me on the " biggest" package instead of the big. They also had me on several movie and sport packages I had never requested. I asked for them to correct it, they apologized and said it was corrected.
From that point my bills were still extremely high and I was disputing the $280 bill I had suddenly received.
In May, 2007 we were told that a payment we had made of $120 had been reversed. We took our bank statement into our local office and showed Charter proof it had been paid. That money has still not been refunded back to our account.

Currently, our service is still being billed for the "bigger" cable package now instead of the "big", which is nearly a $30 per month difference. We also still show the $120 payment as being reversed, although we already showed our bank statements for proof that it has not been. More so recently while looking at our July, 2007 statement it is showing 4 different purchases for pornography at nearly $13 each, that we did not make. We were both at work at the time the purchases were supposedly made. This does not include any additional taxes or late fees charter has continuosly piled on our bill. They currently are sending us bills saying we are past due by $450.

I have contacted their corporate office. I received 3 or so messages from the lady at the corporate offices, after leaving several of my own last month. About 2 weeks ago she finally called during the hours I told her someone would be home. The conversation lasted only a minute, she was very quick to get off the phone and didn't even get all of the information for the complaint for me. She also advised me she would call within one week. About a week later I called charter to see the status of my account, they advised me there were notes on the account that someone would contact me from corporate by Monday to "explain" the bill. That was 2 weeks or more ago.

In the last 2-3 weeks I have probably left their corporate office 10-15 different messages to contact me so we could get the billing corrected on my account. As of today, which is July 22, 2007, I still have not had a return phone call from their corporate office.
I am very seriously afraid they will disconnect my service again although I have paid money to them and have tried to correct the billing. They are obviously unwilling to cooperate and return my calls.
