Debt is for trash bill. Credit management contacted my parents on Wednesday XXXX XXXX, 2015 regarding a delinquent balance ( that was never delinquent ). Told them the dollar amount and threatened to place a lien on their house. All thus after my parents told them that the debt did not belong to them and they were contacting the wrong person. They again contacted my parents again on XXXX XXXX, 2015 even after the conversation on Wednesday when my parents told them they were contacting the wrong person.
