Well...since I've started reading and accepting advice here, I've settled about $70K in cc debt for about $25K total.
Citibank was easiest to deal with and held more than half of that total and they settled very quickly in one lump sum amount for each card. Very nice, very easy, no pain.
Chase held about $20K and they were only marginally more difficult.
So...
Discover is at about $6K but refuse to talk about settling, telling me that they do not settle. I know this is untrue but don't bring that up...just keep on calling week after week and offering gradually-increasing amounts.
