Vodacom billing me for Data not used

<p>Since Janauary 2017 i have been experiencing issues with Vodacom and their billing system. Im on Vodacom Red contract, unlimited calls and 5 gig data package. I pay R2000 all inclusive and that is why I signed up for this contract. Since January this year my data of 5 gig is finished by 10 th day of the month which is totally impossible. I have been phoning several times and get told they will have a look at it but cant really tell me what is the solution to this.</p> <p>My phone is set up to do updates only over wifi so it is impossible for me to use 5gigs in 10 days. Im consisdering canceling my contract as I now have to buy extra data on 11th of each month. Nobody is assisting from Vodacom side. I have had it now with Vodacom, I can see my usage on my phone and it does not correspond with Vodacom's usage as per their account info. People with similar contracts as me use their phones as hotspots which i dont even do and their data last longer.</p> <p>Everyone be aware of this contract!!!!!!!!!!!!</p>
