Vodacom \ Gamemine unknown charges

I only noticed now that I have been charged a subscription of R4.35 per day for Gamemine since the 20th January 2020. I have never subscribed for these services. I sent an SMS to 31050 with the message "STOP ALL" and (also cancelled subscriptions with Tobi) but was notified that I am not subscribed to any WASP service. I spoke to the call centre and they cannot tell me where these come from either. I checked all my devices and there are no subscriptions. I contacted the Gamemine and they told me I have no subscriptions linked to my phone number. It is an outrage that Vodacom do not pick up and stop such phishing schemes - likely because they make money from it. I expect Vodacom to come to the party and provide me the detail as to what this was for, and then refund me.
