Vodacom *****s 1.5Bb from me

I bought 1Gb data on Saturday 22/08/2015 and it never got activated. Then I bought another 500 meg on 24/08/2015. This also never got activated. <br> Today I phoned customer care to find out what has happened to my data and the consultant told me I have used it all. <br> Firstly, my data has been off most of the time, since i have been waiting for an sms telling me its activated - which I never received. So it is IMPOSSIBLE to have used that amount of data. Secondly, I use wi-fi at my house and at work. <br> The consultant tried to make it sound like I was updating or downloading, which was certainly not doing.<br> As usual Vodacom the network is pathetic, not only at dealing with customers but at service providing
