Vodacom Fibre pathetic service

I had to set up everything myself on my own router, and then days later they bring a router. That doesn't work with my NAS. So this got chucked back in the cupboard. Now I'm hit with a Fair Usage Policy, when I know for a fact MTN doesn't have any such nonsense on Fibre. I'm very sure when I sold this it was stated there's no throttling or shaping on the line.
