I think that's besides the point. We have lawyers, doctors, teachers using this technology. Imagine how much worse it's going to get.
OP's position is that someone else should reimburse them for their own errors. Are you siding with the OP and suggesting that if a lawyer, doctor, or teacher misused the technology that they too shouldn't be responsible for it?
Because that's the crux of this. Responsibility.
It might not be the sole responsibility of the customer service agent, but it is certainly their fault for giving bad advice.
It is completely reasonable to rely on the public statements of a company.
That said unless a someone at the company steps up, this seems like an issue for something like small claims court.
