answer: #Person2# wants to increase the amount of #Person2#'s L/C. #Person1# asks #Person2# to fill in an application form and pay for it.
documents: #Person1#: Good afternoon. Which service do you require.
  #Person2#: I need to increase the amount of my L / C. It's quite a new one ; I opened it 12 days ago.
  #Person1#: What you need to do is apply for an amendment on your existing L / C.
  #Person2#: How do I go about that?
  #Person1#: You'll need to fill in this application form and there is a charge of 30 US dollars for this.
  #Person2#: OK, you can take that from my account. I'll fill in the form now.
  #Person1#: Thanks. Yes. . . that's all in order. What we will do now is send the L / C amendment to the negotiating bank. As soon as we know anything, we'll contact you.
