On March 14,2013 I received my bill from Comcast and it had almost doubled so I called customer service and told them I wanted to cancel. The CS rep said they would upgrade my package and internet service for about $90.
I said ok and two hours later I received a confirmation e-mail with the agreed price. Next month I got the same high bill that I complained about. I ended up taking a copy of my e-mail to the comcast office and basically was told they would not honor the price I was promised but would give me another price that wasn't even as good as I had then.
They told me this in a message left on my phone and then without me agreeing to the new package deal which was worse than I had, they downgraded my package and charge me $30 for breaking my contract and gave me a lot worse package for more money than I had before I called them. They refused to honor a written agreement between me (a Customer ) and them.
