You have repeatedly ignored our written requests for payment of the above-noted invoice, and you have not contacted us with any explanation.
Consequently, unless we receive your payment in full by the end of the business day on August 30, 2005, we will be forced to take the unpleasant step of turning your account over to a professional collection agency. We would rather not do this since it will result in damage to your personal credit rating.
To prevent us from taking this final step, please pay your debt in full by the end of the business day on Friday, August 30, 2005.
We urge you to give this matter your full attention now, before it is too late; please send your payment to us immediately.
