Clientele seems to be giving me the run around with regards to refunding me on a debit order they made without my consent

I gave Clientele reps my name, ID number and phone number after they said I will receive a voucher from clientele to shop with. But then on the 23rd of October I saw a clientele debit order that took R305 from bank account without my consent as I never gave them my account number nor signed anything that says I'm registered for life cover. I called the call center and they cancelled the cover and promised to give me a refund within 15 days. I did not get it so I called them again and now they say I will get it within 30 days and 30 days are about ro end I still haven't received my refund. What they are doing is ***** and *****ing as I'm a student and I really need my money back.
