I see no problems regarding pings, either local nor international... international pings are either on par or better with Telkom's unshaped and local is sub < 60ms.
As for shaping, Celemasiko, I understand your frustration, but this product was never designed for P2P/Torrents, and this has been indicated multiple times. No guarantees were ever made regarding it, and if you're looking for guaranteed bandwidth for BitTorrent then you're best off getting a Diginet line from Telkom for a couple of grand a month. In an ideal world we would all be flying at multiple mbits/s with no limitations, but the climate being as it is means that it is not cost effective for UUNet to provide unlimited BitTorrent traffic on their network. The cost to them becomes far too great to justify providing the product primarily due to Telkom and the rates they charge.
Naturally it comes down to money, reducing BitTorrent traffic makes it immediately more viable for them than keeping it enabled. This is not a perfect world and what you're looking for is a perfect world in which you can do what you want when you want. It unfortunately doesn't work this way, purely because of cost. If bandwidth cost next to nothing here in South Africa, as it does in countries such as the US and UK, then naturally we would see more diverse products, faster speeds and less restrictions, but that's years away. At a 30:1 contention ratio you are paying for a 30th of the maximum bandwidth the account supports (in this case 512K), you could say you are paying for a dedicated 30th (1:1), at 512K therefore the guarantee can only be placed at approx. 17K (slower than a modem) when the link is running at peak. Unfortunately, when using BitTorrent you have people using substantially more than their alotted 17K, meaning it eats into everyone elses bandwidth. Normally this wouldn't be a problem, as you have a minority of high bandwidth users that get subsidised by the majority of low bandwidth users and generally everyone is happy because the low bandwidth users see no decrease in performance while the high bandwidth users can happily download away at maximum speeds.
BitTorrent changes this, it's a far more aggressive application than, lets say, FTP or HTTP downloads (even if you used something such as FlashGet - BitTorrent is way worse) and has a habit of substantially degrading the network for other users. UUNet isn't the only ISP to see this problem, Telkom experiences it too (though certainly not as badly) as will IS (though their pricing makes it less desirable for home users), and so do many international ISP's. The difference comes in regarding US ISP's and SA ISP's that they can afford many times more bandwidth than we can and they can therefore handle the load far better than we can.
