Vodacom is *****ing from SA users

I have been using vodacom for a very very long time now and now I am thinking of porting my number to a different network. few weeks back when I buy air time it just disappear and when I call vodacom they say I have subscribed to WASP which they say its taking R50 and R7, as far as my mind can recall I have never subscribe to anything which can take that much of my money and I believe that most SA citizen are victim of this (the something happen to my sister and they told her its WASP). 3 day ago I bought just for you minutes which I never receive to date and I even log a call for that and they say they will get back to me but they never did. vodacom is *****ing and its not far what they are doing. Vodacom should fix their system or they will loose may customers just like me.
