8 GIG IN ONE MONTH??????

I usually use 3Gig data during a month and occasionally have to top up with an extra 1 Gig. This month so far I have had to top up to 8Gig - I called Vodacom on 082155 to enquire about the high usage and first spoke to Kanye who, after 15 minutes on the phone came back to me with the comment \you've been on the internet the whole time
