Debt review

I have been under debt review since April 2014, and the agreed amount by the Court Order is has been paid over since then. I received statements and the amount owed is more than the amount when I started under debt review. How will I ever settle this if you charge me more than what I am paying every month? Please explain to me how I will be debt free as per the Court Order granted within 7 years if my balance is getting more and more????
