Hunky Dory - not subscribed but paid for EACH DAY

I noticed my airtime decreasing over a time now without any knowledge on how as I have data on my phone. After noticing R30 less on my airtime in three days, I went to a Vodacom shop and they showed me I subscribed for Hunky Dory - which I never did, I don't have kids playing on my phone so how is this possible. I tried to google "hunky dory", the only thing that comes up is hello peter complaints with this same situation from Vodacom customers only - this raises a concern with me as this is Vodacom customers only which means it comes from Vodacom themself. I lost how many airtime without giving permission to subsribe to something, Vodacom I expect full return of my airtime as you have done with other clients as none of us subcribed for anything and you have been taking R10 each day!!!!
