Mzansi Debt Clinic

I am very dissatisfied customer of Mzansi Debt Clinic, I app**** for debt construction in 2017 before the process could start I have managed to clear myself I called them to inform them that I wont be needing their services they demanded a fee for their admin and to close my file which I duly paid, fast forward to this week I app**** for car finance and I was declined because I am under debt review, I tried calling the debt counsellor yesterday and today their number no longer exist I don't know how to fix this without a clearance letter from them
