I owe around $1000 on a credit card that was written off in early 2008. It was originally just for 300 or 500 but, with interest and fees is up there. I got a call from a "law firm"/debt collector in regards to this. I do not dispute that I owe it. He told me enough details over the phone that I know they could validate it, even if I tried to deny it. So, here's my dilema: what rights do I have in regards to setting up payment arrangements? How much is "enough" to pay each month? My income is minimal and I would like to pay $100 per month.
