According to the terms and conditions of the promissory note I signed on [DATE], I am obligated to tender my payment in the amount of $[AMOUNT] to you on [DATE].
I have just been informed that funds which were to be paid to me prior to the due date on the note, have been delayed.
Needless to say, this comes as a great disappointment to me.
I have been assured, however, that these funds will be in my possession by [DATE].
I am requesting that the due date on the promissory note be extended for a period of one month and a just consideration for said extension be suggested by you.
I will look forward to your early response.
