Txu energy Deposit ripoff Nationwide

I'm so disappointed with txu energy. They charge you like crazy every month. Also I paid a 556 deposit to get theor service. In march I was told my contract was about to be up and I needed to renew and two different people told me. So I called a few weeks later and had to talk to an oversees lady and she told me it didn't. Well I assumed  she didn't know what she was talking about since two people told me it was up. So they charged me 295 dollars for early cancelation and I call today and they say since I was told by a forigner that it didn't they can't reimburse me my money. I am so disappointed in txu I just want my money.
