Attorney's? Call them ASAP. They will obtain a judgement against you - which is the last thing you want on your credit report. Negotiate with them - you might be surprised to see how willing they are to settle on an amount. If you own $1,033, I would say that I might be able to pay $600, but I can only do about $100 a month - or whatever you feel you can handle.
Point is - call them. Do not ignore them. And negotiate. And don't forget to add that when you have satisfied this, you will expect them to delete any and all references to this account from your credit reports.
