Mann Bracken: Is it difficult to deal with them?

Mann Bracken for NCO Portfolio took me to court without my knowledge in 2005 and a judgement was issued against me for $994. The original debt was a Cross Country Bank CC for $250 in which I applied for one month before my 18th birthday in 2000. I admit I was irresponsible by applying for it so young and then giving the card to my first real boyfriend. I only made 1 payment of $70 while I still had the card and thought the rest of the card was paid off by him as promised (idiot move). I had no clue about the rest of any of this happened until I recently pulled my credit report in order to consolidate my student loans and know what I was dealing with exactly. I never applied for anything else since 2000 not even when I purchased my car. Now I got a correspondence in the mail from NCO, they are trying to collect on that same Credit Card in the amount of $1,183.50. If they (Mann Bracken/NCO Portfolio) already submitted the debt to go to court via Man Bracken can they collect twice and if I settle with them for this amount they are offering….who will take this judgement off of my credit ASAP.
