Clientele Legal Policy Cancellation

I was ******* into joining the clientele legal policy by one of their agents in February, I was told that she was only checking if I do qualify and that a consultant would call me to confirm whether or not I would want to go ahead with it. That never happened, instead I got an SMS from them stating that they would start debiting R200 from my account, and they went ahead with it without my authorization. I tried emailing and calling their centre to cancel the policy, but no luck. My number is automatically rejected now every time I try to call their centre. They`ve been debiting R200 from my account for 3 months now, and today I woke up to another R200 debit. Its really frustrating, their service is poor. I would really appreciate assistance in cancelling this policy and getting my refund as I did not authorize any of those debit orders that they made.
