Dear Austin parker,
A number of reminders have been sent to remind you about paying the overdue balance on your account at our bank. we still await a response or a payment from you. A non serious attitude towards the payment of overdue amounts can result in a blemished past record. Do let us know via calls or letters of any situation that is making it difficult for you to pay so that alternate methods of payment can be looked into.
Sincerely,
George
