Would this hold up in court as actually "knowing" your customer if you let an AI handle it?
It's a pain in the ass exactly because it's critical at a level of "oops we lost our license to do business", and part of the pain is the unending edge cases that require personal attention that any attempt to automate will immediately have to break out to a real person. So you end up keeping your headcount of the expensive people and layering another expense on top for no value.
AI agents are a screening tool to wees out interactions that would be a cost to the business rather than an opportunity ie in non-specialised situations (for example customer queries where the answer is the first question in the faq).
They are not a solution to highly specific b2b workflows, and especially not when a regulatory body will always be at couple of decades behind technology.
