Vodafone — Unnecessarily deducting balanced against some unsubscribed service

On May 17 10:06AM I got message saying that your balance 7rs has been deducted against "Games and Videos service".
I have never subscribed to any such service.

I tried to check if I subscribed to any such service by checking in VI APP. but i didnt found anything there.

I sent STOP message to 155223 which says that you haven't subscribed to any VAS service.

I tried calling call center but I think I can never reach them.
This is not the first time happened to me, his happened several times so i need to raise a complaint and need answer on this.

I want to know who allowed Vodafone to deduct my balance.
I never sent any message to Vodafone to activate nay service.

Vodafone is just looted my 200-300 balance from last 5-6 months, i need a proper answer
