Hi! My name is Katrine Miller and I need to check my bank balance.
Can you tell me your account number, please?
I don't have my account number of pin but I can verify my security information.
And what was the name of the pet you had as a child?
My pets name was Buddy and my date of birth is 04/04/1990.
I am sorry, but I cannot authenticate you with the information you have provided.

Is there anything else that I can do for you?
No, that is all. Thank you for your help.
Thank you and goodbye.
