Telkom Smart Home Deals

I have been looking at telkom's Smart home deals.

And they are way to cheap for what they are selling. its cant simply be that cheap for so much?

where is the catch?

have a look at the home supreme and home premium.

I mean you cant even get a 40meg vdsl line for that price?

I cant find any small print on their packages,

What exactly does unlimited Night surfer mean? Am I able to download an unlimited amount between 12-6 ? is it only browsing data and not torrents?

Has any one here any any experience with the Telkom Smart packages or perhaps know anything about them?
