Vodacom Data contract 5Gig used too quickly without browsing or downloading anything

<p>On 27 May 2015 I took up a 24 month data contract with 5Gig from Vodacom with number ********** 492. The first month, our 5Gig data was finished within 3 days and then the second month within 8 days after we switched our wifi on and off on our devices. After this occurred I inquired from Vodacom as to why our data is getting used up so quickly, and they told me that while our data modem is on and our devices wifi is on, our Megs will be used up although we don’t browse or download anything. This is very frustrating because before we went over to Vodacom, we had a Telkom data contract for 5Gigs as well per month and not once did we run out of data while having that Telkom contract. We have had to put our Vodacom modem off the whole time and then on for a few minutes in the evenings to browse or download stuff and still our data lasts 21 days at maximum out of a full month. I am very disappointed and am not interested in paying for this service or contract anymore, as it’s a very inconvenient service and I can’t see why our data must be used up even without us browsing or downloading anything. I would like to cancel this contract. </p>
