********* debiting my bank account

********* debiting my bank account. I cancelled my contract on the 1st of June 2022, by the 15th June when I called to confirm my cancellation I was informed by the consultant that there is no cancellation request which was very upsetting as I cancelled on the app that was available to me. My account was debited on the 25 June 2022, today again my account was billed with R499 when I called in to the call center once again I'm informed that the cancellation was not processed, hence my account was billed. I want my money refunded immediately and my bank details removed from the systems immediately because i am unable to remove my bank details.
