Mean words cannot hurt a bank. Threats cannot hurt a bank. Paper trails, though, are terrifying to regulated institutions. Your bank’s customer support representatives are taught to evaluate whether someone looks like they’re competent and collecting a paper trail. If they are, the CS rep is supposed to stop touching the case immediately and instead escalate them to a supervisor or to the legal department.
The legal department (or an analogous group – it is different at every bank) is not scored on cases resolved per week. They are scored on regulatory incidents per quarter, and their target for success is likely zero. Shockingly senior people will be involved to avert regulatory incidents.
Great stuff, and great advice.
