Poor service by XDS credit bureau

This credit bureau is a disgrace, I loadged a dispute with them 2 months ago and no feedback has been given to me. Every time I phone them I am told that the they have ruled in my favour but no confirmation has been sent to me. All their consultants keep telling me one think, Kefilwe will send it just now for the for the past week now, all these consultants claim to have spoken to her but her highness Kefilwe will not send the confirmation and actually update my credit record.
