Dear Felix
This is to confirm our recent telephone conversation regarding the past due balance of your account.
As mentioned in our conversation, the current balance on the account is $ [dollar amount], of which $ [dollar amount]is now past due for payment. We will look forward to receiving your check within the next week to clear the past due charges on your account. Once these charges have been cleared, we will be in a position to review the current credit arrangements for your account. Presently, however, all orders are currently being referred to us. Your check to clear the past due balance must be received before future shipments on credit can be made.
Your cooperation and prompt attention to this matter will be greatly appreciated. If you have any questions regarding your account, please do not hesitate to contact us.
