Ask a Lawyer and Get Answers to Your Legal Questions
I will try and help. You probably won't like this answer, but please don't shoot the messenger.
There are a number of problems with you idea. The first is proof. First you have to prove that they had a duty not to do whatever you allege they did, and then that they in fact did it. Secondly and more importantly, you need to show damages. Embarrassment is not compensable, so unless you can show a financial business loss, you will be unable to recover.
Not every slight has a legal remedy. Sure, this was probably frustrating and embarrassing, but unless you suffered a considerable financial loss, it is not worth it to try to sue BOFA.
I hope this helps.
