Poor service

Last year August I sent them an email requesting how to exit the debt review process, this was based on the fact that one of their consultants requested me to settle the last outstanding account on my own (which I did because they are useless). when I asked him why have I been paying them to do this on behalf he cancelled the debit order and I was handed over to their lawyers for non payment. On 24 Nov 2022 they sent me an email that it would take 10-15 days to issue my clearance certificate after informing their lawyers of their actions. Last weekend i was informed I cant upgrade my cellphone because Debt busters listed me as a high risk. Since the last correspondences in Nov I never had any interaction with them. When logging in to their app I discovered that they reflected that I have not made any payments. They are utterly useless and unprofessional as it is clear that they do not communicate within their own departments as between email and telephone conversations they cant resolve my request.
