Dear Mr. Marsh: Thank you for your check for $200. The balance remaining on your account is now $600. Since you have requested an extension, we offer you the following payment plan: $200 by the 15th of the month for the next three months. If you have another plan in mind, please telephone my office so that we may discuss it. Otherwise, we will expect your next check for $200 on September 15. Sincerely yours,
