TXU Energy company I moved to Harlingen, from St. Louis Missouri. not knowing the reputation of any of the electric companies. Dallas, Texas

I moved to harlingen texas from st louis missouri and needed an electric company.  I chose txu energy and they requested $150 deposit and i signed a 2 year contract. even with a contract my rates increased, when i called to ask why they said it was because i went over a certain usage that month.  then after 1 year they contacted me and told me i needed to send another deposit of $140.  when i asked them why, they said it was because i was a late pay.  my service was never disconnected, and i paid after the date was due but never went over my late period.  i knew i was going to change carriers so throughout the next few months i would call them and inquire about my deposit and was always reassured i would get it.  then my contract expired, i paid my last bill and call to request my deposit.  they told me the deposit of $290 was used inthe last 6 months for my late fees... which i never received any bill indicating such charges even existed.this company is the worst and i have never heard of such a large company getting by when this type of service.  i hope the complaints will finally cause some action against them.... jlo harlingen, tx
