Shocking service from the NCC

I am shocked with the service received from the NCC. I had logged the complaint and is rather straight forward issue with the dealership. I was successful with the Ombudsman, however the dealership an I did not agree on the usage calculation of the vehicle. Thus I had to approach the NCC. The basis of the claim was around the usage of the vehicle,. The case was appointed to Badisa Boikanyo who sat with the case for more than a year without even approaching the dealership. I had sent him more than 30 unanswered emails and had approached the management for assistance. Which he still ignored and only responded when Prudence Moilwa was asked for assistance. Andile Mange was also approached for assistance prior to this, but was treated the same. The dealership was approached and made his statement. I then responded with my response to later then be ignored by Badisa after siding with the dealership. I made valid statements just to be ignored and still asked him for proof of the dealerships statements. He still ignores my emails, Andile Mange ignores my emails and Prudence Moilwa also ignores. After battling for more than 18 months, receiving one response from Badisa and asking for proof and correct usage calculations. Still to be ignored. Waiting for more than a year for a response, more that 30 emails following up, asking for correct calculations and begging for assistance, just to be ignored without and proof given or even getting a response. Badisa Boikanyo was upset that I had approached his management and tried to prove a point by siding with the dealership. Even after proof was given, but nothing from the dealerships end. This case was clear and the evidence is clear. How should clients be treated fairly if the NCC cannot deal with cases like this. I am shocked, they should be the primary regulator of consumer-regulator business interaction.
