Terrible service

I have been trying to get some help with paid letters for my outstanding 2 accounts, I sent emails and I called debt manager to assist me from last year. I paid this outstanding 2 accounts in full and I requested my name to be removed from debt review, the debt manager is not active to help me. I tried to communicate with my debt manager but the service is poor, he doesn't follow through my emails even when I call a lot of times i cant get hold of him. The statements that he sent to me they are all incorrect and contributions are going to the closed accounts. I am disappointed with credix debt management and I need to someone to help me
