So how could you let IT know? You could call customer service, but I have a hard time thinking that a low-wage CS person would pass this along to the IT group.
I've recently had to work with an airline on a similar problem recently and there's not much difference between the low-wage CS person and the low-wage "third party" developer sitting in the same bloody cubicle which is why the error happened in the first place. 😉 Send an email and hope everyone does their job. It's a whole lot less frustrating that way.
