Debit order continues despite cancellation for unjustifiable premium increase

I cancelled my car insurance with Pineapple at the beginning of January 2025, specifying that From 01/02/2025 I would be with another insurer. I changed because Pineapple had increased my premiuim by 12% after no claims (ever), an older vehicle with an older driver. I could not understand it and the rep Basetsana Selematsela could not justify it, despite being helpful and understanding. She assured me that "Your policy has been cancelled effective 01/02/2025.We look forward to having you return!" I was then surprised to see that my account was debited by Pineapple again for February. When I issued a cancellation letter, I received a response in 3 minutes. Now that I have reached out querying why I was debited again, no one is responding. Really not impressed.
