The NCC doesn't deserve to be a Consumer Commission

I had logged a case with the NCC about a C&K Money line (***) in 2015, they refused to cancel my contract and refund my money. this was even though I requested for cancellation the very next day as there's a 5 day cooling off period. Ntshengedzeni Netshiinganwe from the NCC was dealing with the matter, for over to 3 years I made follow ups and he advised they were busy with it. He said that there were a lot of similar complaints and they wanted to consolidate them into one. Now nobody responds to my mail, I suppose they let the case die a natural death. Why couldn't he tell me he can't assist from the beginning.
