DMC refused to give me a discount for a prescribed debt

I called DMC wanting to settle my debt that I had for a long time, number 1 the debt is already prescribed but they refuse to update my profile so I called them to settle this account. I got very rude lady from customer service first she talked like she is very tired, and when I told her that I would like to pay for my account that was handed over, I told he i know the debt is prescribed and I would like a discount. She refused to give a discount it's like they enjoy being on people's credit report, I have a right to get a discount DMC why don't you want to remove yourselfs in people's credit report
