text: Alex: Good afternoon. There's a problem with my credit card.
  Steven: Good morning. Could you tell me briefly what the problem is?
  Alex: I can see on my balance slip that there's a charge I didn't make.
  Steven: What is it for?
  Alex: For a birthday cake.
  Steven: How much is it?
  Alex: 15 GBP. But I did not buy it
  Steven: Did you let anyone use your card last week?
  Alex: No
  Steven: All right, I've made note of that in our system and we'll contact you to set things straight within 7 days.
  Alex: Thank you. Will it burden my account until then?
  Steven: I'm afraid it will. But I hope everything will be resolved to your satisfaction.
  Alex: I hope so too.
  Steven: Is there anything else I can help you with?
  Alex: No. Thank you.
  Steven: Thank you for contacting us and using our mobile services. Have a good day!
