Debiting my account after 5 months of notice of cancellation issued

Cancelled my car insurance with IWyze and received a notice of cancellation letter on 18 January 2025 after they could not reduce my premiums. Cancellation reasons provided to IWyze and also noted on the notice of cancellation letter on 18 January 2025. There was no further communication from IWyze regarding the car insurance and I happily took out insurance with another company. On 25 June 2025 (without communication or notification from IWyze), my account was debited by IWyze. Bad business practice, debiting my account without any communication/ notification whilst the policy has been cancelled for more than 5 months, pathetic. Also, just because they have access to my "old" details including my account number DOES NOT GIVE THEM THE RIGHT TO ACCESS MY ACCOUNT AS AND WHEN THEY PLEASE. What about compliance to POPIA???
