TXU Energy Scaming people for money by advertising prepaid options Internet

 I signed up for prepaid because I thought that I was managed close and properly. They said that I was to receive emails and text messages to let me know when my balance was getting low and also to keep me from getting disconnected. They are sending the me messages whenever they feel like it. My lights had been cut off and 2 hours
later I got a message that stated that I had been disconnected and after I was disconnected I got a message that said for me to add funds to avoid being disconnected. After speaking to a agent I was told that no matter what the time stamp is on the message that I receive I am still responsible for all charges. She said they are not responsible for when I get the message as long as I receive it. I told they lady that that just did not make sense. I signed up so that I could be alerted before it got to that point as she said that it was my responsibility. At this point I feel that they are doing it just to get an  extra $50 out of me. This is the second time that this has happened and each time they come up with something different. If
I had $50 to give to them I would not be using Prepaid. They evens sent the caution of disconnect after it had already been disconnected with a time stamp of 7:32 am at 11:45. I told her that I could send a screen shot of it and she tried to argue with me still that it was not their fault. I will be posting this here and everywhere I can to warn people that this electricity company is  COMPLETE SCAM! Go with anyone accept them. Their understanding is completely ZERO and they are going to do what they want with your account and money anyway.
