text: Vivianne: Hi 
  Vivianne: I received a letter today from your company
  Vivianne: It seems that there is a problem on my account
  Louis: Good afternoon Vivianne
  Louis: Can you please give me your client account number?
  Vivianne: It's 34034099
  Louis: Our records state that the last bill has not been paid
  Vivianne: Well that's odd, I made a transfer last week
  Louis: It says here that we received a payment of €33.30. This covers the bill for November
  Vivianne: I see. I must have made a mistake
  Louis: You just need to settle €30.40 in order to fix this
  Vivianne: Can I do this online?
  Louis: I'm afraid not, you will need to go to your local office where you live
  Vivianne: Ok
  Vivianne: Thank you for your assistance
  Louis: Anything else I can help you with?
  Vivianne: No, thank you
  Louis: Wish you a good day :)
target: Vivianne hasn't settled the last payment for her account. To unlock it, she has to issue the outstanding amount in the local office.
