Subscription to Tapgamz and VIP Games

My company recently changed from MTN to Vodacom and suddenly I discover that I am subscribed to Tapgames and VIP Games without me ever registering for those services Being a business number, I only discovered a couple of months later that I was subscribed and got a massive bill. They have now stopped the subscription but I want them to return my money as I have NEVER downloaded any games or whatever they offer I have never subscribed to anything and I delete any messages that might ask me to subscribe Has Vodacom got shares in these companies ? This is a ******* This seems to happen to Vodacom subscribers more that any other. I never had a problem with Cell C or MTN and I have been with them for years
