Most of the times, collectors don't extend settlements whenever consumers desire. But at least, you can negotiate with them and give a try to it. Maybe, there are some offers available for people like you trying to pay their debt.
Also, note that the collectors are allowed to add interests on the total debt only if the creditors have authorized them to do so. Besides, check the statutes in your state to know the permissible interest charges that can be levied legally.
