I'm not happy I've been patient enough with DMC DEBT MANAGEMENT AND TRANSUNION

Im not happy with DMC Debt Management & transunion... I paid up my debt with them on 1 June 2022 but the account still appears as an active account on my credit report & whenever I call the consultants tell me the query has been escalated with transunion I should wait for 7 days since beginning of August I've been waiting . It's September now and my name has not been cleared!!!!!! And I even tried to dispute the account as instructed by one of the consultants from DMC on my transunion acc but still nothing, what else do I have to do to remove the account?
