The article leaves me with questions. Why $7,000 even? That isn't a correct refund, is it over or short.
Why the lawsuit if the bank corrected the error? Oh,that's right, the bank didn't explain that any exact error was corrected.
Bummer that the bank was in part trying to do the right thing and may end up with a class action suit for it.
With all the bells and whistles the big banks promised to implement to prevent problems, how did this happen?
Is there a potential class behind this, or was the error isolated?
