Debt collector is assignee of creditor and sued for payment of my deceased husband's medical bill. Issue was between Insurance company and medical provider (submitted wrong billing code to insurance) as a result, they were not paid and so unpaid bill was presented to me for payment. I called insurance and told them about billing error so medical provider corrected coding error and resubmitted for payment. Insurance fully paid account before hearing. However, collection company/debt collector or creditor did not file "Acknowledgment of Satisfaction of Judgment". Debt collector filed Abstract of Judgment and placed lien on my real properties for collection of additional fees, charges, etc. Demand payment before release of lien and provide report to credit bureaus as fully paid.
