Please compare Letter A with Letter B, and comment on both of them. Then, revise your favorite one for effectiveness. Add any information if necessary. Letter A Dear Sirs As you know we had trouble with you earlier this year when you wouldn’t pay for your goods. We were forced to take legal proceedings to recover the money. This e-mail is just to tell you that we wish to terminate any business arrangements with your company as you are unreliable. Yours faithfully Letter B Dear Sirs You will remember that during the summer of this year we wrote to you repeatedly asking you to settle your account with us. At that time you did not make payment and we were forced to take legal proceedings. Although we have now recovered this money, the time involved and the attitude of your company, have forced us to make the reluctant decision not to supply goods to you in the near future. Yours faithfully
