TXU sent me a bill for $490.90 for a home that I have managed and closed(sold) more tha ayear ago which I don't have the records anymore and I no longer work for that management companynd can no longer ask them to pay for this bill if there is any because after closing they asked to sign a contract that I can't any more utility payments 30 days after closing. I had several accounts with TXU in 2008, now I have 2 and I never missed any payments with any of these accounts and I was questioning TXU why after more than a year they are sending me a bill for that much. I don't believed I have missed paying this account. They told me to make a payment arrangement for their inefficiency?
