I want to resolve this off my CBR bal is growing is it legal

Hello is anyone still on here. Oh well To the expects please. I have the same situation as RM. I just pulled my credit report and found a debt to midland credit management (whom I don't know). In my CBR I can see the account number listed as starting with Assciates. My account with Associates did go into write-off sometime in 2002. Midland has never contacted me and the balance on my account was about $1200 when it went into write-off but the balance as of Nov 2006 CBR is approximately $2000. They have contracted it out to one of their outside agencies called ARS National(they won't give me their address). I wanna dispute the balance and am thinkin I may need the validation too before I can resolve this issue. Can I also write this letter to them too. On my CBReport they have no info abt last pmt date, schedule payments, no Charge off date, no date when account was opened. All they have is the high credit=$1591 and the bal/past due amount = $1973.
Is it also legal for them to continue to grow the balance even though the account is charged off?
Please advice me on what to do
Thanks BNF from North Carolina
