txu energy TXU refuses to issue leter of credit for a 6 year customer Internet

I have purchased a house that we are going to remodel and flip in Keller Texas. The electric provider is Tri County (TXU is not a valid option) as a result I need a letter of credit, so I don’t have to pay a deposit; from TXU my electric provider at my house in Irving for the last 6 years. I have made 5 phone calls over the last two weeks now and TXU Simply Refuses to send me the letter, or address the issue.
 
For the last two weeks I have been using a generator that I borrowed from a friend, all because of “Power Inc.” and there not wanting to lose a customer in a move.              
 
Can you help in motivating them to do basic, decent customer service?
 
Copies of this letter are also being forwarded to the BBB, all local news outlets, as well as may customer complaint sites as I can locate. This is just wrong on so many levels
 
Up until this last December I was actually a contractor for TXU working on their new web site, Now I’m having a very hard time trying to justify staying a customer, and that was the second time I worked for them.
