Vodacom additional content payment ****

I took out a second cell phone contract in December and recently discovered that I had been billed an additional R580 per month since February for additional content. The purpose of taking out a R279 per month contract was precisely for affordability. I had absolutely no knowledge and did not authorize the billing of additional content. When I called Vodacom they told me to go and check subscriptions in my Google account which I checked and found no subscriptions at all. The Vodacom person did not dispute this but rather said that she would immediately cancel the additional content. I have now continued to be billed for this additional content without having any subscriptions in place. This clearly indicates internal Vodacom staff complicity in this **** which suggest that these people are getting financial rewards for initiating these unauthorized payments on customer accounts.
