As you have paid this debt, you should send a letter disputing the debt to the debt collector currently collecting the debt. Explain in your letter that you have paid the debt and provide the collector with a copy of the payment receipt.

In addition, review your credit report to see if the debt is being reported. If it is and the information is inaccurate, dispute the debt with the consumer reporting agency.

You can obtain a copy of your credit report at http://www.annualcreditreport.com/. The steps for disputing information on your credit report is also available on the site.
