Any call center systematically asks to repeat all information, any administration asks for papers and all its dependencies. (For example in France in order to get married you need both the birth certificate, pacs certificate and pacs non-dissolution certificate. All of these contain the same information)

This is not a problem that needs LLMs to be solved. It’s a data entry and retrieval with consent problem.

Yes, better customer service is not bounded by physics but it might be bounded by competence or maybe even malice if companies simply want to make the experience horrible so no one ever calls back (suggest starting with Hanlon's razor first however). Regardless, having an agent on our side, fighting against these two forces would be great.

I don't know if there is anything to back up the hypothesis that they indeed want their systems to be horrible. It is possible, but sometimes, I want to pay more (buy more insurance coverage, etc), so sometimes our goals are actually aligned yet it is still a painful process. Therefore, I think it is more likely that the problem is competence.
