Woodforest Bank fraudulant theft Fredericksburg, Texas

As of July 4, 2017, my bankbook showed a balance of over $400.  July 5, 2017, I received several notices that I was over $400 in my account.  July 6, 2017, I personally went to the bank.  We found identity theft.  The lady who worked there was polite and helpful.  She informed me that it would take approximately ten days.  A few days later, I received a letter from the bank giving me credit of $439.71 on my account to use until the investigation was completed.  On July 30, 2017, I received a notice from the bank that I was minus over 129.00.  On August 1, 2017, I went into the bank to dispute the account.  The bank did not return my overdrawn charges, they went retroactive before the fraud was discovered, and after arguing with the employees of the bank for almost an hour, I decided to close out my account.  It cost me $200.00 extra to close out my account.  That brings a total of $639.71 they refuse to correct or give me.  It's not going to break me, but it sure does hurt losing that much money, and they refused to further investigate what I was trying to tell them.  I used simple mathematics to demonstrate how and why they were wrong.  They continued to look and the screen and tell me that not all of those overdraft charges had to be honored.  I'm a little miffed.
