Unauthorised Charges Added to Account as "Purchased Content 2"

My bill seemed higher than normal and on investigating I discovered an extra charge for "Purchased Content 2". The call centre tells me that it is for something called ATP Golden Pass at R8 per day, related to Tennis of which I have no interest in this sport. This is not a service/app I would sign up for and it feels like a ****. I have also seen there is another review on Hello Peter relating to this same charge that was just added onto someone's account. Please could this be investigated and the charges reversed.
