Out of Bundle Data costs

I have 2 Data bundles with Mweb.<br> This month for the f1st time I have exceeded my Data by 849.27 megs for which I have been charged R1388.51 which works out to R1.65 per meg.<br> My contract is 5gigs at 5cents per meg.<br> How do they justify such a large increase.<br> This is through Vodacom<br> So I am not sure if this is a Vodacom charge or MWEB are marking it up to this \*******"percentage.<br> Even Cell C are adverting 99cents out of bundle data.<br> On my other Data bundle on the same account I still have Data available and if I don't use it by Friday there is no carry over even though I have paid for it yet when you are over you get an exorbitant charge.<br> Even sadder is that the Mweb billing department have not responded in 3 days yet Icasa have twice responded to me and I have been a customer of MWeb's for maybe 8 years.<br> The good news is that I have been informed by ICasa that they will be investigating transparency on the out of Bundle charges this year so we might not be \""**********\"" in the future.<br> An increase from 5cents to R1.67 per meg and no carry over but you pay for every meg you are over"""
