Ok, so I phoned 155, and according to Sydney their system is faulty. The 500mb ad-hoc bundle for Aug has been loaded, and get this, to be activated on the 31st of Aug?! Idiots!
So Sydney logged a service request, which will be done in one working day, iow end of Monday!
Bottom line is that this was actioned on the 2nd of August, so I loose out on 5 days of my bundle, plus I am too scared to use my connection, as I don't want to be charged out of bundle.
v3g, early warning that I am going to push on your button to get this billing sorted out. Actually, thinking about it now I will be using my connection as I should ... I don't care about the Vodacom system being screwed ... If I didn't follow up on this, I would have gotten a fat surprise at the end of the month.
So according to me, I have 6mb left on 75mb bolt-on, and then it will automatically switch over to my 500mb ad-hoc bundle ... And Vodacom, don't even try to charge me out of bundle ... you won't get away with it!
