I don't think they steal your data... They really don't need to...
Additionally. Their 2GB Package Here https://www.afrihost.com/site/product/mobile_data?src=website_nav
saos R145per month. So there's no issue.
They were running what many call a "promotion" Which means they gave a way a bit of free data in a few select packages until it expires on said date. This said data was mentioned to all on the signup page, Emails, newsletters, facebook, twitter... Pretty much everywhere.
Not sure if #afrihost will comment. But this is what I've gathered.
I do advise if you're unhappy, don't stress yourself by staying unhappy. Find someone to keep you happy (Y)
