6. Поставьте части письма в правильном порядке. Yours sincerely R. Costello (Sr) Credit Controller With reference to my letter of 10 August, I enclose copy invoices wh ich made up your June statement, the balance of which still remains outstanding. Having dealt with you for some time, we are concerned that we have neither received your remittance nor any explanation as to why the balance of $ 2,000 has not been cleared. We would appreciate it if you could either reply with an explanation or send us a cheque to clear the account within the next seven days. Looking forward to hearing from you. Dear Mr Giordianino
