*****ing Money from Pensioners

I've had a prepaid Vodacom sim card for many years. Recently (last few months) my airtime started disappearing, and my family thought I was mad. But I'm a pensioner and I keep tabs on my airtime. They checked all my application permissions, bought me data, made sure I was connected to the wifi at home. But yet my air time kept disappearing every day. No one believed me, and I ended up with no airtime in my account on more than one occasion, without having made any calls. Then a friend mentions that I may have subscriptions, so we phone customer care, and sure enough theres some TWO Vlive (no idea what that is) subscriptions on my account. I never signed up for these. Disgusted that vodacom can ***** money like this. Now customer care won't even tell me how long I was subscribed for, so I can prove to my family I'm not crazy.
