Fast usage of Data

Dear Vodacom<br> I recently bought (19 August 2015) a 1gig data bundle from your Vodacom store in Cape Gate for my wifi router. I used the data for work purposes i.e. emails and paid R149 for the bundle. To my surprise the data was depleted less than 24 hours after buying which i found to be ridiculous particularly since i did not use the bundle for downloading massive files. I have been and are a MTN customer and has never experienced such fast data usage ever and i use this for my personal usage. <br> I am now forced to buy more data which i find utterly ridiculous.<br> Data cost is already so high in South Africa and to have it depleted so fast feels like day light *******.<br> I find this to be unacceptable and i hope that you (Vodacom) will address this matter.
