Data goes over cap - Vodacom does not care

Hi. <br> <br> My company has a data package with Vodacom which caps at R150. Today my computer went into a download loop and in 30min went over the cap and downloaded 2 gigs above this. <br> <br> 1) Why did the cap not kick in sooner. Surely this is a very simple thing to manage. <br> 2) Is this a strategy from Vodacom to get more money<br> <br> I can not pay this excess bill as the reason why a cap was placed on the sim. <br> <br> Please can Vodacom respond and at least meet me half way as this is a failure on their system
