Getting ********** then a Nonsense Reply

My original Query: I get 300Mb data on my Smart M contract. My Mobile data usage for 1 to 27 December - 333Mb (33Mb over). I purchased a 1Gb Bundle on the 27th. The 27th of December to 31 Dec: 455Mb used of the 1 GB Bundle. Hence, 545Mb still available. January arrives and 300Mb Smart M data bundle plus 545Mb data remaining = 845Mb data remaining. Data used from 1 to 31 January = 348Mb. In other words by the end of January I should have 497Mb remaining. However I get charged an extra R515 for Data Usage? How does this work?<br> <br> The response I received from Maraine informs me of Vodacom's T&C's (which supports my query) and then if I need additional assistance I must contact them again. In other words, we didn't bother to read your mail properly, please waste your time again by letting us know that. <br> <br> So, to Vodacom: I have two issues:<br> 1. You are overcharging me for data<br> 2. Your Customer Care replies are a waste of time. Fix it please.<br>
