Is that what your lawyer told you? Cuz unless it's a mega corp lawsuits are expensive and they often settle if the demand is under a certain amount and there is a real or mostly-real complaint.
Plus a series of judgements does a good job of illustrating to others that all allegations were false, and were looked at by a court (possibly multiple times) to determine if they had any validity.
3 judgements in your favor is a good rebuttal if it ever comes up again...
What good would that do? OP would likely get a few thousand dollars, and the bank would make that in profits in less time than it just took you to read the word "profits".
You'd end up costing yourself money, just in the sheer time it would take to do it.
