Bad Service

I mailed The Motor Industry Ombudsman of South Africa and logged a case against a car dealer with that sold me a car without specifying that it had issue which I only picked up on the second day of having the car with me back in July 2017, this case has been awaiting feedback from the case manager ever since and till today June 14th 2018 nothing from the MIOSA case manager, what can be causing this delay?

I am being told I need to call every month till I get feedback, basically just wait for him.
