Charged out of Bundle Rates but still have In Bundle Data

<p>As soon as i get a sms to say i am almost out of data i log on to My Vodacom and load a data bundle. I just went onto the My Vodacom app and was shocked to see my bill at R2586.05 I phoned into vodacom (Reference 1_ ********** 7) only to be told that i am being charged out of bundle rates.... but wait for it... i still have data 1.39Gigs. How is this even possible. I am extremely angry !!! No SMS was sent to me and i am always purchasing data to avoid out of bundle charges!!!! Thank you Vodacom for rewarding my loyalty!!! So mad!!!!</p>
