I bank with Brazos Valley Schools Credit Union. My debit card number was stolen, I believe at the Bryan HEB (last place I used it before fraudulent purchases popped up).
Fraud protection instantly went into gear and stopped it dead. There were something like two charges in Arlington, one at McDonalds and one at a liquor store there before the card was frozen. I called, ad they were very good at explaining just what happened. The main hassle was waiting for a new card to be issued, but the fraud protection folks were right on it, and I received a notice within 2 days. Within 48 hours to the two fraudulent charges were credited back to my account.
They have been seriously on the ball with me since I joined them. Not suggesting you switch from Aggieland to them, but they are good at dealing with this.
