Why all of a sudden softcap?

I was phoned by a telkom sales representative trying to sell me fibre. I advised that I did not want it as it has a 50gb softcap. He advised that I go for 10 mbps dsl upgrade with no softcap, so I say yes. Now I still have a softcap and cant even access the telkom website. Telkom have only given me grief since day one. If you dont want my money, I' ll take it elsewhere. Simple as that. I download game updates. If I have never had this issue with uncapped before. I am utterly dusgusted yet again. And I also now have an ulcer!!!
