Clarity on the outstanding fee

I have an issue regarding my contract I have been seeking for almost a week and nothing’s positive coming out of it who ever is assisting me via emails does not fully help me because I have been asking for clarity each and every figure that what’s the amount for instead they are sending me some vague financial figures and when I am asking them what is that outstanding figure for they just sent me an email notifying that my query has been closed and if there will be same query they will close my case to me it sounded so unfair because surely why i am asking because I don’t understand I want one thing from them clarity because right now to me I feel unfairly billed
