I filed for bankruptcy a few months ago. I was discharged August 31,2009.?

and now Im still getting letters from people stating I owe them money and they are on my bankruptcy. What do I need to do?

Same thing is happening to me. In fact the creditor never stopped calling and still calls today. I was given this advice by a consumer advocate. Send a certified letter with return receipt telling them about the BK and send a copy of the discharge to them. By sending it certified you now have proof that they have notice. Be absolutely sure that they were included in the BK. If they continue to call after they receive the letter, then talk to an attorney and take action against them.

The answer below is on the referenced website. If you have a copy of the discharge you should just send it in response to the letters you are getting. Otherwise you can follow the instructions below:

What can the debtor do if a creditor attempts to collect a discharged debt after the case is concluded?

If a creditor attempts collection efforts on a discharged debt, the debtor can file a motion with the court, reporting the action and asking that the case be reopened to address the matter. The bankruptcy court will often do so to ensure that the discharge is not violated. The discharge constitutes a permanent statutory injunction prohibiting creditors from taking any action, including the filing of a lawsuit, designed to collect a discharged debt. A creditor can be sanctioned by the court for violating the discharge injunction. The normal sanction for violating the discharge injunction is civil contempt, which is often punishable by a fine.
