No I mean less than R750, ADSL line + Uncapped @ R590 + voice line @ R148 = R748
If you sign up to keep your ADSL line with Telkom for 12 months you will get a 25% discount (Thanks ShaneZN for the heads up on this one)
I firmly believe in keeping your line with Telkom and not your ISP as it makes switching a seemless event. Too many tales of people having their lines cancelled when trying to switch ISP and then spending weeks without an ADSL line (the horror :wtf

So signing up for 12 months and getting 25% off was a no brainer for me at least.
