****mers who are Unresponsive

Why do I have an outstanding balance even after setting the account after receiving a settlement discount? Why are my email queries ignored? Why have I not received the paid up letter I have been requesting? Why even after receiving all payments made, is the account having a balance (which goes up) everytime. I can log on now to find a different amount and log in a few hours later to find a new balance amount (which has gone up) and this is the case everyday. Please provide my paid up letter and stop sending me settlement discount offers when the account is already settled
