Dear Paul smith,
You might be expecting a claim on your account balance of $640 that remains overdue. Though efforts have been made to resolve this issue but the payment haven’t been made from your side neither have you notified us of a problem. If the payment is not received four days from now, your account will be turned over to our Collection Agency. This would certainly result in your good credibility being affected.
Sincerely,
Eako smith
