Ridiculous Vodacom Prices

I've had contract with Vodacom since my very first phone. I've always been mostly happy with cell phone reception, customer services, etc. Until now! For the. First time in this new year I want to buy my usual 30 day data bundle. I've always thought the prices to be quite high, but then we live im South Africa, which gives us limited options as far as data plans are concerned. I've been fine with paying the R149 for 1GB, which I can use as and when I want. I've never had the need for a night owl bundle, because I sleep at night - what would be the point. So I dial *135# and do the selections to get my 1GB for 30 days at R149, and imagine my great surprise when it is now available at a cheaper R100! How great is that! But wait! This is the only silver lining.... I now suddenly pay R100 for 500mb of data AND 500mb of night owl. Which means I pay R50 for something I WILL NEVER USE! ***! What nonsense is this?? Why have they changed? Why can't I just get my 1GB and be done with it? It is absolutely ridiculous! And all the 30 day bundles are divided up like that. I DON'T NEED NIGHT OWL DATA! WHY TAKE AWAY MY CHOICE IN THE MATTER?! For years now people have been complaining about the services provided by cellular networks. And instead of listening to the customer, they just go ahead and do what they want. How is that providing the best service possible? I am so disappointed and will no longer suggest anyone sign with Vodacom. It's just not worth the money.
