Sounds like a nightmare. Whenever organisations (usually my bank) try to use such questions to determine if I am who I say I am my replies consist of "I don't know", "I can't remember" and "maybe xxxx?" After much humming and hawing I usually pass the check but it always leaves me feeling that I'd be much hapier if they refused than taking my awful non-answers as good enough.
