very unhappy with DC Partners

I am currently under debt review. DC partners are not handling my distributions for my creditors correctly. I noticed that they did not pay my full amount as they should have. In January 2022 they only paid half the amount that they should have, but took the whole amount for interest as well as their part I had to pay. When i sent a query they sent me another statement for April and deducted interest AGAIN as well as their part. The moneys not paid should have gone straight to my accounts. I would like to handle my own payments as it doesn't seem like they know how to help. What can I do.
