From their perspective even if they can't pass it on, making you provide it as early as possible before you've reached a human ensures you'll have it ready when the human requests it.

How many callers just hang up at the automated first query for the information?

Having recently dealt with some brutal rental car phone support situations, I'm convinced these companies prioritize getting callers to just give up with the minimum of resources expended on their part.

Should you actually reach the live person they want you locked and loaded to not waste their time waiting.

I hate the future.
