1GB for 3 days... NOT!!!

So, I'm new to Vodacom prepaid and inserts my simcard on 10 March. I then get this sms at 23:19 on 11/03/2016: \Congratulations on your new smart phone! We've given you 1GB free for the next 3 days to download all your apps and set-up your phone. Your free data is valid until 13-MAR-2016.\" <br> <br> So I'm downloading and updating software throughout 12 March and at 22:23 still had 253,56 MB left, which I will use on the last day. So on 13 March I'm busy updating the last of the software when I get this sms at 08:00 stating : \"You have been paying R2 per 1MB since 7am.Buy a daily or 30 day bundle from as little as 43c per MB.\"<br> <br> I'm sorry, what!!!!! That was not even 2 days!!<br> <br> Let's do the maths: 11 March 23:19 - 12 March 23:19 is 24 hours. From 12 March 23:19 - 13 March 07:00 is 7 hours and 41 minutes. So, a TOTAL of 31 hours 41 minutes!!!!!<br> <br> If the initial sms stated that the deal will end on 13 March at 07:00 then I would have made a plan to get all my updates done by then. But the way the sms was worded it gave the impression that it will end at 23:59. And why was the initial sms sent at 23:19 on the \"first\" day and not 07:00??<br> <br> This is disgusting!! ********** at best."
