Bank levy and garnishment

I am currently working with a debt settlement company and have settled 2 of my unsecured credit card debts. One of my other creditors (Chase) has hired an Arkansas law office and is threatening to garnish and levy me. It has already gone through arbitration and they have a judgement against me. Do I have any options? I know I owe the debt, but we had catastrophic events (health and business losses) that led to this situation. I am doing my best to save and pay settlements. How much notice will I have of a bank levy or a garnishment?
