Vodacom DATA ****

I tried to arrange with Vodacom to block my phone from not using data when my data bundle is depleted. I contacted Vodacom and the response was that they can add a block to the account, but the block will stop all my communications, i.e. phone calls, sms's and then DATA. According to me this is a **** because, when my data bundle is depleted, Vodacom charges me an exuberant amount of R2.00 per MB. So why would they give you the option to block your data, answer: they make money. I want to block my data when it's depleted, not my calls and SMS's. I'm after all the one paying for this. I should have a choice in the matter. It's time that we a consumers stand by what is right and demand better services.
