What do I do if a debt collector filed a Income Execution Order against me and the information is incorect?

1) The company has been uncooperative responding to my requests for information concerning this alleged debt. To this day I still have no idea where or with who this debt originated from. 2) Five years ago they tried to freeze/take money from my bank accounts all in a two month period. For what ever reason they were unsuccessful. No money was taken. 3) Three years ago they had an attorney file a suite in Livingston County NY Supreme Court. I was unable to address this issue due to lack of information concerning the date or time of the hearing both from the debt collector and the courts. I thought I was entitled to face my accuser and defend myself at this time. 4) The information on the pending Income Execution Order is incorrect. I have not been employed for about two years. I have never been an employee of the company listed. Is the Income Execution Order somehow legal or just another scare tactic?
