The question I have is this....why was the outstanding balance not paid on time, and allowed to accumulate to the point of confusion? Timely payment results in fewer billing problems.

If the work was done and accepted payment must be made. There is no reason why a vendor should have to wait more than thirty days until you receive payment unless it was part of the agreement at the time you ordered the work.

You admit that there is still approximately $1,600.00 due. She said the work was done two years ago. If this is correct she has been incredibly patient with you. If it it had been me I would have had you up in front of a judge 60 to 90 days after the delinquency occurred.
