Vodacom says they can't help with disappearing airtime

Everyone has at least two sim cards a t home but not even one family member use their Vodacom number for anything but receiving calls only; their airtime keeps disappearing and not even Vodacom knows why. For the last few Vodacom recharges, my airtime keeps disappearing after recharge. I first tried to cancel whatever subscription there might be account, alas, there is nothing; I do not have any subscriptions but my airtime keeps disappearing. I called the Vodacom helpline and they tell me they can't see anything. But I see airtime disappearing on my side.

I even got an sms this morning at 2am, saying "I'm getting SMS's saying : "Thank you for buying Wushine WarShip R5." I don't even know what this Wushine Warship is. It's crazy that Vodacom cannot see that R 5 has been deducted from my account. I'm even deducted for out of bundles data when I don't even use my Vodacom sim on a smartphone. They claim I used my data on Vodacom Kicka when I never even seen Vodacom Kicka device except on media. Finally, the agent said there is nothing she can do for me; I said to her, I guess the only solution for me is to stop loading Vodacom airtime. Maybe this poor service will help me break my Vodacom addiction and go elsewhere where my money is appreciated. Like many insurers, the relationship is good when they take your money but when they have to assist you, you have to climb hills and mountains for something that is your right as a customer to receive, a service. Use Vodacom at your own peril.
