Help me out of My Debt Hero please!

Pls help me get out of debtreview. Last year 2023, I was under a lot financial stress bcoz of the increasing interest rates and prices of things. I approached My Debthero for help after seeing an advert on facebook. At the time I was really struggling financially as my car repayments increased by over 1and half thousand rands thereby straining my budget too thin. Some agent explained to me that My Debthero is there to help ppl in situations like mine and I believed that...I was promised that I will get my repayments to decrease and I was pleased to have to save a little over 1thousand rands. What they failed to tell me was that the repayment period was going to be doubled. I learnt about that after I read and studied all their documents ...also found out that they charged me an amount of over 1thousand rands monthly for their services which shocked me! I contacted them via email and told them that I want out, they rep**** by telling me that I cannot get out...I want out asap. I want to manage my car repayment my own way and don't want them to charge me for that as I cannot afford them. Recently I was called by their attorney telling me to fill in some forms and affidavits binding me to a contract with them. I can't do that as I want nothing to do with them anymore. I thank them for relieving my stress at the beginning of our conversations while I was naive enough to think that I had found some relief. P.S. I noticed also that the balance in my car repayment statements is not decreasing at all. I am paying monthly but it seems like I am not paying at all.
