No transparency in advertising.

I received an advert to say if I buy airtime for R12 I would receive bonus airtime worth R25. I had over 50 minutes free, over R40 airtime and over 3 gig data in my phone when I decided to take on the special. To my surprise, after having made to calls more than 15min were taken from my minutes whilst I had just received bonus airtime. I contacted call center and to my surprise was informed that Vodacom used my bonus airtime for my Internet surfing/Internet. Why would I buy R12 airtime only for the bonus airtime to be used for Internet? What is my data for then? I feel vodacom is not transparent in their advertising and has cheated me the consumer by not being transparent. Now I bought airtime I did not need because I thought I would be able to use the free bonus airtime to call my friend. Vodacom is a **** and as a consumer, I feel ******* and want my minutes back. <br> Had I known the free bonus airtime was not for voice to voice calls, air would not have bought the airtime and would've bought power hour instead.<br> <br> I want my minutes back and they can take their data from my 3 gig like it's always been. Stop ******** consumers.<br>
