Mother signed up by unknown party for subscription services

The same day my mother received her new phone, she was subscribed to one or more services that charged at least R7 per day. I phoned Vodacom customer care but your answering machine stopped me from speaking to a human being. I then e-mailed the ***** division, which took a few days to respond. Unfortunately, they were not helpful and told me to SMS a number to stop the subscriptions even though I had told them I do not live with my mother and that she does not know how to send SMSes. They also said I should contact generic customer service to deal with the *****. That is really passing the buck. Today I finally managed to get to my mother and sent and SMS from her phone to stop all subscription services. I also phoned customer service again and again could not speak to a human being. My mother needs her airtime back as she never subscribed to any services. She would not know how to do so in the first place. I am putting her cell number in one of the fields of this complaint form.
