True story:
My dad refuses to do any business with BoA. He hasn't done any business with them since 1963 when he and his first wife moved from Oakland to Ventura. Why? Well, it is simple. BoA made an error in his account, he went to close his account in anticipation of moving, and was given $750 more than he could account for. He argued with the teller, he argued with the head teller, he argued with the manager. Finally, beaten down, he took the money and has never done business with BoA since. I do all my banking with BoA, hoping they will make a similar mistake with me.
