There's been suspicious behavior on my account! Frequent money transfers of $10 have been taken out. Help!
Could I get your full name, please?
I'm Katarina Miller. My pin is 0312, but I can't remember my account number.
Right, and your PIN as well please.
The pin is actually 0314. 
Can you tell me your account number, please?
I just don't remember it. I am 93 years old and am a bit forgetful. 
Could you provide your date of birth, please?
I can barely remember my name, much less my date of birth!
I am sorry, but I cannot authenticate you with the information you have provided.
Oh dear. If only my puppy hadn't eaten the paper with the account number on it!
Can you tell me your account number, please?
Still don't know it. Do you have a problem remembering, too?
I am sorry, but I cannot authenticate you with the information you have provided.
Oh, dear, what a mess!
Thank you and goodbye.
Goodbye.
Thank you and goodbye.
