Missing airtime

Good day

Today I loaded my Topup contract with some airtime to buy some data. Then I noticed my airtime disappearing. Send vodacom a message to find out what's going on.

Only to find Im magically subscribed to gaming content for R10 per day. I did not subscribe to this service I don't even play games on my phone. But airtime gone and vodacom doesn't care as always. My main problem here is, how is it possible that a random company or service just signed me up on to there services with out me knowing. And how is it possible that they just have access to my account?

Vodacom cant even answer me on that. So short and sweet, your account is open for anyone by the looks of things.
