Distuging service

To date I'm still listed as haveling an account with Blu lable after now 2 years of the contract been paid up. Someone contacted and says that the bureau has been sent the communication but it's not true even said I must follow up the 6 weeks they promised has cone and gone and still no joy. I don't get why this company tempers with my credit profile. I will lodge a formal complaint with the NCR/Ombudsman for consumers as I have given ample time for this issue to be resolved
