I lost my debit card and before I could cancel it, somebody withdrew $300 at an ATM.
Stay calm, can I get your full name please?
Jane Doe
May I have your account number Ms. Doe?
I forgot.
I can verify your account if you give me your date of birth and answer two security questions.
I don't know my birth date.
I am sorry, but I cannot authenticate you with the information you have provided.
sigh
Can you try to remember your birthday? 
I can't.
What bank do you use?
I don't know that either.
I am sorry but I can't help you unless you provide your DOB
this is frustrating
What was your mother's maiden name?
I don't know. Never mind. Forget it.
Thank you and goodbye.
