Are you a vodacom salesman that you push this service so hard? The only reason this bundle remotely makes sense is because their other bolt-ons are ridiculously priced to begin with,so rather than buying a bundle more than big enough to last you the month you'd need to stagger your work and buy a small bundle to get connected for an hour
I fail to see the usefulness for an hourlong bundle of such a silly size and at a crap price,especially considering the time it could take to cap that,assuming you got 22mbps connection you could finish that bundle literally in under a minute
The effort required to buy such a bundle is also nonsense for what you get
MTN's uncapped-for-an-hour bolton makes more sense,and even that is pretty meek
