Vodacom data a mockery

<p>I have a 5gig data contract on ********** 629. For at least 3 times this year I paid a bill of over R4000. My latest bill for data amounts to over R6000. I queried this on 13 July 2016 and was informed I would receive feedback within 24 - 48 hours. Subsequent to this I called twice, the last time was last Thursday when I was told that the matter was still under investigation. Well, the amount was just debited off my account and I am to assume that my query means nothing. Why would I run a bill of over R6000 when I know that I only have 5gig on that contract. What just happened is shameful and I feel betrayed by the poor service rendered by Vodacom. Moreover, expecting me to pay such a huge bill without a reasonable explanation is shameful. Vodacom data is turning out to be a mockery!</p>
