Of course this creditor is likely violating the Discharge of 11 USC sec. 524. There is a chance that the creditor is not doing so knowingly since the creditor presumably has a signed reaff. agreement in hand, and may not be aware that the Court did not approve the reaffirmation. So...if you had a lawyer in the case, discuss with him or her the desirability of filing a Motion for Contempt against this creditor. If you had no lawyer, it would likely be a good idea to retain one. But I do think that a single warning letter to the creditor, informing it of all the relevant facts and written in a polite but firm manner, might stop the harassment. And the fact that you did give a warning will look better in your motion papers if you must go for contempt.
