Clientele agents lying to us in order to get a sale

On the 26th of November a young lady in Wonderpark mall called Naledi assisted me in registering for Clientele perks. She told me that this a 30 day free service and I will get a message at the end of my 30 days to confirm if I still want to continue with the rewards. My account will be debited from then if I agree. Come to my surprise few days later my account was debited and it's a blocked debit. I de-registered the account on the app 3 days after registering.I tried to talk to her she told me there's nothing she can do I must call to find out why clientele debited my account. Why must your agents lie to us in order to get a sale. I want my refund because clientele is doing us dirty with these rewards that's why we cannot reverse.
