Dear Mr Giordianino

With reference to my letter of 10 August, I enclose copy invoices which 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.

Yours sincerely R. Costello (Sr) Credit Controller
