Something is wrong with debt safe

Something is not right, I am paying every month but the money I owe to creditors does not go down, this month it will be down next month it goes up, I don't understand how I can pay R4700 and then only about few hundred rands my credit goes down, then next month it goes up again buy few hundred rands... I am thinking someone is eating my money. Is painful paying every month with no progress.
