Worst customer service

A lady who was promoting clientele perks in Westgate numetro said she is promoting the program. You get discounts and cashback for uploading receipts on the app, I signed up because I thought I have nothing to lose by uploading slips every time I purchase something and get a coupon month end. She then asked for bank account, which I asked why she needs it, she said it's to redeem the coupons and cashback.

Now when I check my banking app I have a debit order of R160, for clientele perks. Which I was not told about. I have sent countless emails on their customer service asking them to cancel the policy. They only asked for ID number. That was it. I can't afford to pay R160 per month. Why can't you just cancel the policy that was sold under false pretense 😡😡
