Clientele Royalty Rewards Voucher Issue

I’m specifically referring to Clientele Royalty Rewards who phone me and offered me rewards if for eg in the form of shopping vouchers. They assured me that I have a 5 day cooling off period. I accepted the offer. I contacted Clientele Royalty Rewards within the cooling off period on 17 Mar 2026. They then responded to my e mail on 17 Mar 2026 (could be automated) stating “Your ticket - Cancellation of Royalty Voucher Contract - has been closed”. I assumed the contract was cancelled. The Clientele consultant requested that I download the Clientele. The call was ended after all my personal information was given and the Consultant was going to call me back to explain how the app works. This did not materialise. My banking account was to my shock debited for the first time on 24th of March with R170.00 without having agreed upon a fixed date of payment. This happened on April and May 2026. I then contacted them again via e mail again on 29 April 2026 stating that I cancelled the contract. Again an automated message from them stating that the ticket was closed. I repeated this again on 5 May. So my banking account was now debited 3 times with R170 without me activating the app or receiving and feedback or vouchers from Clientele Royalty Rewards. Standard Bank strangely is also BLOCKED from reversing these debits despite proof from my side that I cancelled this contract.
