What can I do?

Hi.I got enticed by this add from Clientele about joining their Royalty programme.I was told there would be benefit including free vouchers at selected partner stores.So I was encouraged to pay R170.00 every month. It was also claimed that there would be free spin,but that does not even respond to touch.

What hurts the most is that I am realizing that I give to such a big company,hard earned money,for free.I tried to cancel the debit orders which I approved earlier,but I was told even my bank was not allowed to cancel Clientele subscriptions.
