Does anyone know if this is harassment or what?

I live in michigan, 2years ago my husband and I filed for bankruptcy, we let everything go back even our house. The mortgage company filed for foreclosure posted it in local paper even had posted date of sale auction in the paper.. we moved of course and someone has padlocked the doors. We still get notices of taxes and mowing of the yard we have told them we don't own it and have a discharge on our bankruptcy. how do we get this to stop? does anyone know?
