Unauthorized deductions

I took my children to Nu Metro cinema in Canal Walk and I don't know how many agents gathered around me to offer free movie tickets if I just download the clientele app on my phone, I was assured many many times that it is free and that I would receive 2 x movie vouchers. The agents were very quick with talking, even taking my phone and inserting information a few times BUT was reassured no debit orders will be talen Toy surprise I see an amount of R160 has been debited and it is an 'authorized' debit so I can't even reverse it. My bank says I will have to pay R75 to have the funds reversed but there is no guarantee that next month the debit won't be taken again I want this canceled, this is an unauthorized debit order, this is *****, how many children have they done this to.

I want someone to call me and cancel this nonsense I don't even know what I'm paying R160 for? I'm going to take this further if I don't get assistance
