Occasionally debtors will find themselves in a situation where they are continuously being hounded by creditors. The debts have been sold and resold and many times debtors are not even sure who they owe funds to anymore. Unfortunately, this can make those debtors vulnerable to scams. If a debtor receives a call from an aggressive creditor demanding payment and the creditor is offering a substantial discount the debtor may be tempted to take the deal-even though the debtor does not know the exact source of the debt.
