I am being harassed by debt collectors in regards to creditors I put on my bankruptcy. How can I stop this?

You should send a copy of your schedules and your discharge to all the creditors who are still contacting you. It is advised you do the following:
File a complaint with the Federal Trade Commission. There is a website with easy instructions on how to do this. It is against the law to pursue a debt that was placed on your bankruptcy and was discharged. For further information http://www.consumer.ftc.gov/articles/0149-debt-collection
