Dispute of Content Service Opera Telecom

On 28 May I called Vodacom & dispute a Opera Telecom amount of R43.00 per day against my account. The advice was to send a sms to 30333 to stop all. I did not give any authorization to any outside company to debit my account with Vodacom R43.00 per day. When I logged a Service request the person from accounts called me back after few days to advice that they do have an agreement with the people. The total amount of R1032 was debit against my account without my permission. What type of Service Provider is Vodacom who does not care and does not protect their clients. is this may be another **** where Vodacom maybe have part in the ****?.
