Shaha Finlease — Want to know how much they can settle

Had a credit card with SCB in 2010. I Lost the card during those days and now I get a letter to pay 51, 28, 02. They are demanding this much amount to be paid now.
I had some amtto be paid at that time around 3000 but now it is increased so much.im ready to pay the min amount in thousands I don't have that much money.
How much amount they can lower it to so that I can settle this completely.
