Rude & unhelpful staff & company

A bond settled in full in March 2018 still reflecting. Lodged a dispute and when following-up no one can assist. Called and speaking with an agent at 4:55pm & told that the department i'm looking for closes at 5 so they cant help me. Then told i am being transferred to the correct department only for the call to be cut. What ridiculous, pathetic, rude & non-existent service. How does the NCR allow such non-existent service from the main credit bureau in SA?
