Settlement on my account

My capfin account has be handled to legal department due to not paying account, i've made arrangements to pay each 500 to pay starting this month but I came to my mind to settle the account, in which ill be paying 30% off less on my balance, so Ive decided to settle my account so Ive reserved the payment of 500 so I can settle. I called and spoke to the lady i dont remember her name in which she told me that they'll be an agent who will be calling me.The agent called me ant to my surprice she told me she cant help me with settlement as i didnt pay the 500, she's not even sure if the account is with them, the agent was so rude that she even drooped the call while I was speaking to her.What I need is to settle the accout wuth the 30% discount I was told off.
