As far as I know, this product has not actually been launched yet, it will be launched soon (within the month).
Also, note that until now there were no Uncapped Do Bundles (e.g. like "Do 2", "Do Basic" etc.), but I think some are in the works, which will result in a cheaper total package. As far as I know, existing "Do Basic" and "Do Advanced" customers will automatically get the discount, as long as they have the appropriate line and it is with Telkom (and not an ISP).
