SIR, I have made several applications to you for the settlement of your account, now a long time over due.
Our clerk has frequently called for it, but has not been fortunate enough to have an interview with you. I have a very large amount to make up by the end of this month, and must beg of you to give attention to it before that time.
You must be aware that the account has already run far beyond my usual term of credit.
Awaiting an early settlement,
I am, Sir, Your obedient Servant,
Your Name here
